truth values for the given homework problem. A.) True...since it satisfies when x is square root of 2 B.) False...Because domain is real numbers... C.) False.. Because domain is real numbers...
1. True ---- > for x equal to sqrt(2) 2. False ---- > negative number multiplied by a negative number is always positive 3. False ---- > Square a number can never be less than zero
homework problems solution: a ) true when x is square root of 2 b ) false because square of nay number can't be equal to -1 c ) false because square of a number can't be less than 0
📄 Homework problem 1. TRUE, since the domain is real number, we can use x equals root of two, then (√2)^2=2 2. FALSE, because all real numbers result positive when its squared 3. FALSE , because all real numbers result positive when its squared and it greater than zero
it will be true for all the three cases as if we take root 2 for the first one after squarring root will be removed so it satisfies similarly for second root -1 after squarring it willl still be -1 as only root will be removed and same for the third one
Sir, in your last video of data structure where we add a list in a given position what happen if we gave a position which is not existing in our list? Please sir reply.....
ANSWER: both a, b, c are true A:when x equal square root of 2 then x^2=2; B: whan x equal to (-1)^3 then x^2=(-1)^5=-1; C: When x equal to (-1)^3 then X^2=(-1)^5=-1
B is False. You do a mistake , To solve this expression, follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right). So, first, evaluate the expression within the innermost parentheses: (-1)^3 = -1. Now, we have (-1)^3 raised to the power of 2. So, (-1)^3 = -1, and (-1)^3 squared means multiplying -1 by itself, so (-1)^3 squared = (-1) * (-1) = 1. Therefore, the answer is 1. Same rules follow in answer C, so that will be also False
Why this videos are soo underrated i mean... The explainer is just perfect in his job! ❤️💯
bcz people watch it while preparing for exams and they dont have time to like videos
truth values for the given homework problem.
A.) True...since it satisfies when x is square root of 2
B.) False...Because domain is real numbers...
C.) False.. Because domain is real numbers...
A.) is False, because root 2 is an irrational number... and our domain is rational numbers only.
For C wen X= 1/2, x^2
@@kisatsronal256 If x = 1/2, x^2 will be equal to 1/4 which is 0.25.
and 0.25 is greater than zero.

for x^2 = -1 and x^2
i is imaginary🤡
Thankyou Sir you are really helping a lot...very awesome explanation...ek ek topic dhang se clear ho raha hai...Thankyou so much Sir 🙏
1) true sqrt of 2
2) false domain real
3) true 1/2
bruhhh.. 0.5 squared is 0.25 which is still greater than 0, the last one is false.
tommorow is my automata theory exam and i am going to watch your videos in 2X now

🤯wow great
Thanks for this sir,
Someone please tell in ex3 how we would know that to take positive or negative value as to get correct answer?
Hit & Trial most probably, the solution wouldn't be that complicated.
Tqq sir....
Tq so much😊
In 2nd question if we take sq root of -1 And its square will cancel its square and then it give -1 that we wanted
The square change negative in positive so -1^2 will become+1so LHS is not equal to RHS that's if wchic is false
sq root of -1 is a complex number , generally known as iota
homework problems solution:
a ) true when x is square root of 2
b ) false because square of nay number can't be equal to -1
c ) false because square of a number can't be less than 0

Comments not showing
1. When x=root 2
then x^2=2
=>(root 2)^2 = 2
=>2=2
so, Ex(x^2 = 2) is True.
2. false
3. false
what if we put the value of x =1/2 in third part of homework
Who watches comments hit like
can`t we take root values?
Broo nxt video
Sir please complete full syllabus before December 🙏🙏.still I am preparing gate 2021 sir
Sir plz upload the nxt topic fast
a) True
b) False
c) False
Please correct me if I am wrong.
ANSWER: both a, b, c are true
A:when x equal square root of 2 then x^2=2;
B: whan x equal to (-1)^3 then x^2=(-1)^5=-1;
C: When x equal to (-1)^3 then
X^2=(-1)^5=-1
But we take in real numbet form.not square or cube anything.
B is False.
You do a mistake ,
To solve this expression, follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).
So, first, evaluate the expression within the innermost parentheses: (-1)^3 = -1.
Now, we have (-1)^3 raised to the power of 2. So, (-1)^3 = -1, and (-1)^3 squared means multiplying -1 by itself, so (-1)^3 squared = (-1) * (-1) = 1.
Therefore, the answer is 1.
Same rules follow in answer C, so that will be also False
