Question

1. what is the solution of the equation? 36x^2=100

Answer 1

Start with

$36x^2 = 100$

Divide both sides by 36:

$x^2 = \dfrac{100}{36} = \left(\dfrac{10}{6}\right)^2$

Consider the square roots of both sides. This means that we have to consider both signs:

$x = \pm\dfrac{10}{6} = \pm \dfrac{5}{3}$
