The final result can be found in the area formula for a regular octagon: A=2*(1+sqrt 2)s^2.

Amei!
i enjoy your videos . I am stuck at home with covid and it is fun to watch your process with this problem . I am a retired math teacher
The longest way to solve IT)
I just solved it using a function and found the intersection with y At 5 x
Its ok, but last should be catch a2+b2= x, and ab = y then formula apply, I think it will be easy.
1+√5/2 =phi
Wrong!😝😝😝❌❌❌👎👎👎
Здорово!
Também é possível encontrar os valores de a, b e c escrevendo na forma de matriz e fazendo o escalonamento.
[x+y*sqrt(2)]^3=…=(x^3+6*x*y^2)+(3*y*x^2+2y^3)*sqrt(2)=99+70*sqrt(2) .Therefore (1) x*(x^2+6*y^2)=99 ; (2) y*(3*x^2+2*y^2)=70 . (3) x=3*u (4) y=2*v .We substituted (3) in (1) end (4) in (2) . We get : (5) u*(3*u^2+8*v^2)=11 ; (6) v*(27*u^2+8*v^2)=35 . You can guess, that : !!! u=v=1 !!! We get : !!!! x=3 , y=2 !!!! Therefore : [3+2*sqrt(2)]^3=99+70*sqrt(2) . 3+2*sqrt(2)=[1+sqrt(2)]^2 . We get your answer !!! With respect , Lidiy
Typical case of intersection between a circle and a line. Every time there are zero, one or two solution points.
Awsome!

√[125+50√6]=√[a²+2ab+b²]=√(a+b)²=a+b a²+b²=125 2ab=50√6 ab=25√6 25√6=√[2*3*5*5*5*5]=√75*√50 a²=75 a=√75=5√3 b²=50 b=√50=5√2 Answer : 5√3 + 5√2
Its 1(rootx) + i(rootx)=4 (1+i)(rootx)=4 Rootx =4/(1+i) x=[4/(1+i)]^2 x=16/2i x=8/i??
Don't forget 8/i = 8/√(-1). The denominator needs to be rationalized according to some teachers, and that turns out to be helpful here. That can be done by multiplying the entire fraction by i/i=1, resulting in x=8i/(-1), or x=-8i: x = 8/i x = (8/i)(i/i) x = (8•i)/(i•i) x = 8i/(i²) x = 8i/(-1) x = -8i And if you're wondering why the final result in the video says x=±8i, keep in mind that if x=-8i, then -x=8i. Addition is commutative, so you can actually swap x with -x, and it'll still work: √(-8i) + √(8i) = 4 - x=-8i √(8i) + √(-8i) = 4 - x=+8i The video actually provides the math for it, but logic works just as well sometimes. And if you're wondering about the actual values of √(8i) and √(-8i), look into the polar and exponential forms of complex numbers. You should find √(8i) = 2+2i √(-8i) = 2-2i
9:30 ...hmm... sqr(x^2) = |x| = ±x
Note that √(x^2) is not the same as ∜x In any case, solving √(x^2) = 4 gives two answers: x = ±4 But solving √(x^2) = −4 gives no answer. Solving √(expression_1) = expression_2 only has solution when expression_2 ≥ 0 Same logic is used for fourth roots. At 9:30, expression_2 = (−1−√5)/2 < 0, so there is no solution
√(16√8) = 4[2^(3/4)] = 2^(2+3/4) = 2^(11/4) = 64^x = 2^6x 6x = 11/4; x = 11/24
This can be done so much faster. Just square immediately: x + 2✓x✓-x -x = 16 ✓x✓-x = 8 Squaring again gives -x^2 = 64 Which gives x = +- 8i
Or just √(-x²)=8 x = 8/i x = -8i Addition is commutative, so if the sum of √(-8i) and √(+8i) is 4, then the sum of √(+8i) and √(-8i) must also be 4, meaning x = ±8i

5 минут возни - и двойки наконец сократились. А в конце пришлось вспоминать, чему равны a и b. Если бы заранее не записали, не решили бы.
again, like many problems in this category: YOU HAVE TO STATE WHAT IS THE SET THAT YOU ARE LOOKING FOR SOLUTIONS (in this case is R and not C, deducted after the presented solution)
я просто понял сначала что число под корнем не может быть отрицательным и поэтому полюбому x должен быть 0
sqrt(16*sqrt(8))=64^x (16*8^(1/2))^(1/2)=(2^6)^x (2^4*2^(3/2))^1/2)=2^(6*x) (2^(4+3/2))^(1/2)=2^(6*x) (2^(11/2))^(1/2)=2^(6*x) 2^((11/2)*(1/2))=2^(6*x) 2^(11/4)=2^(6*x) 11/4=6*x x=(11/4)/6 x=11/24

or just... use the quadratic formula
What a waste of time sind ink !
You made a mistake. Multiplication is denoted solely by a (), not with the additional central dot.
There are many similar problems, so many people will solve it easier. If you look at the "x²+x" part, you can expect that the equation is {x+(A+1)}(x-A)=x²+{(A+1)-A}x-A(A+1)=x²+x-A(A+1)=0 (A: positive integer). In other words, since A(A+1)=44442222, you just need to find two integers that differ by 1. 44442222 is 44442222=(2222)(20001). Here, adding up the digits of 20001 gives 2+0+0+0+1=3, so that it is a multiple of 3, and 20001=(3)(6667). Therefore, 44442222=(2222)(3)(6667)=(6666)(6667), as a result, we can find that A is 6666. (x+6667)(x-6666)=0 ⇒x=-6667, 6666.
Δε κατάλαβα πως λύνεται
Observation: -44442222<0, meaning the roots differ in sign. Observation: (x-r)(x+s)=0 will result in roots r and -s. In this problem, the coefficient of the x term is positive, so s+(-r) > 0, or s>r. Note the inverted relationship: s+(-r)>0, yet the roots are +r and -s. Once you have 44442222 = 6a(6a+1) , you can substitute a=1111, yielding 6666(6667). 6667 > 6666, making the roots r=6666 , s=-6667 .
