Question

√(x2-36)=8 find x in the problem

Answer 1

$\sqrt{ {x}^{2} - 36 } = 8$
Squaring both sides...

${ (\sqrt{ {x}^{2} - 36 } })^{2} = {8}^{2} \\ {x}^{2} - 36 = 64 \\ {x}^{2} = 64 + 36 \\ {x}^{2} = 100 \\ x = \sqrt{100} \\ x = 10$

Answer 2

Hello users ...

Solution:-
Given that:
√(x² - 36) = 8

Squaring on both sides ...

=> (x² - 36) = 8² = 64

=> x² = 64 + 34 = 100

Taking Square root on both sides .....

=> √x²  = √100

=> x = +10 And -10 Answer
