Question

X^(2)+x^(2)=128
or
x^2+x^2=128

Answer 1

8 =6 since 8 squared is 64 and 64 +64 or 64 times 2 is 128 that’s is your answer.

Explanation:

Answer 2

Explanation:

x^2 + x^2 = 128 Normally you don't do this but rewrite the question

1x^2 + 1x^2 = 128

You actually do use 1 + 1 = 2 First time I've ever done that.

2x^2 = 128 Divide by 2

2x^2/2 = 128 / 2

x^2 = 64 Take the square root of both sides

sqrt(x^2)= sqrt(64)

x = 8
