You are welcome!

Thanks!

Thanks for the appreciation, Unfortunately very few people know and appreciate these critical details.

Thanks a lot, you too have a very nice channel doing good work with simple but tricky problems.

sqrt (i/2)=(1+i)/2, can be checked by De moivre's formula, so the LHS of the equation becomes ((1+i)/2 )+i((1+i)/2)=i which is not equal to the RHS (1) So the equation has only one solution, that is -i/2.

@@LearnwithDrJaved I'm sorry for taking up your time but this poses a question for me: I believe my misconception was in checking my answer in a calculator as such, sqrt(x) + sqrt(-x), then observing an answer as one for both values of x However, if I instead rewrite sqrt(-x) as i(sqrt(x)) we have: sqrt(x) + i(sqrt(x)) which will only work for the singular value of x being -i/2. My question is, why wouldn't these two equations produce the same result? Furthermore, why would ONLY the one where we use i to remove the negative from the square root be valid? Wolframalpha allows us to see the singular solution for the second equation but both solutions for the first equation, so surely both aren't equal to one another, i.e: sqrt(x) + i(sqrt(x)) does NOT equal sqrt(x) + sqrt(-x) Thank you for your time sir.

x+(-x)+2sqrt(-x.x)=1 after squaring both the sides sqrt (-x^2)=1/2 i . sqrt(x^2)=1/2 sqrt (x^2)=1/2i x = -i/2 (as 1/i = -i) I am perplexed how did you get a positive solution.

I understood the problem, sqrt(-(-i/2)) is not equal to sqrt (i/2), it is equal to i.sqrt(i/2). For more clarity please watch ua-cam.com/video/xahuv1UMY20/v-deo.html

@@LearnwithDrJaved Ah ok thank you

taking log x common on the left hand side, remaining terms add to 3/2

You're welcome. Happy solving:-)

Happy equation solving, best of luck.

I could not understand the comment

You can check through logarithmic differentiation, this is what you get for dp/p for an isothermal process.

This story is just one of the great struggles to get some simple formula we use normally. All the best for your future and studies.

Yes 512=8^3, and 2=√4, will give the result in a single step

4V means fourth root, and that is power quarter just V means second root and that is power half

The square root of the given number is an irrational number, you can check with your mobile calculator. The nearest full square number is 818276. And you can evaluate its square root, which comes out to be 904.

31/29=1.066896552, this does not pose any problem if you solve long enough you can find the repeating decimal numbers....

OK we got x=y2^2.5 also we have found that y=2^5 this makes y^0.5=2^2.5 we put this value of 2^2.5 in the expression for x and get x=y.y^0.5 x=y^(3/2)

It MAY work if there are only two terms x^8 and x^4 with a constant.

Technically yes, but you're better off using u-substitution for higher degree polynomials

The answer may be correct bu multiplication by 2 part is not clear.

Any citrus fruit will do, In fact peels of all the citrus fruits show the same behaviour

To solve any Trigonometric equation, one needs to transform them in these forms!

a very nice alternative solution

Simplified by squaring both the sides two times!

@@LearnwithDrJaved same thing with raising both sides by the power of 4.

​​How u got 25 in the second step plz explain 🙏​@@ChavoMysterio

(2x+11)^¼=5^½ [(2x+11)^¼]²=(5^½)² (2x+11)^½=5 [(2x+11)^½]²=5² 2x+11=25 That's how you do it.

(2x+11)^¼=5^½ [(2x+11)^¼]⁴=(5^½)⁴ 2x+11=5² 2x+11=25

Thanks a lot for your appreciation!

Thanks a lot for your appreciation!

It also stops in very cold weather, or humid weather when there is little or no evaporation!

Thanks for the appreciation!

Thanks!!!

Yes, these are the two roots of the equation

x=1 - это решение, но есть и иррациональное решение, как показано на видео

Yes, this is the solution

The mistake lies in the second line from bottom. as 9+7 = 16 and not 18 as shown in your solution!

You are welcome! And thanks for the appreciation.

Yes, interestingly both the solutions are reciprocal of each other

in addition 4 and 5 are also two of the solutions.

Nice fonts🙂

Вам нужно перепроверить это, единственное решение - x = 100, поскольку база журнала равна 10.

Да, вы также можете использовать эту замену...

да, это единственное верное решение

Так умно с твоей стороны! Большой.

первый корень - просто наблюдение, второй - хитрый!

Да, это устно, решение не должно занять более нескольких секунд!

Да, это решения!

пожалуйста

Yes, this step also may be included in the solution

Да, это не должно занять более 5 секунд!

Yes this is a way to get the answer.

A great quick solution, thanks!

Thanks for providing a solution with the method of substitution

-1/3 and -1 are also solutions.
