Question

64 = h²
submit
or
8
or -8

Explanation:

Step1: Solve the square - root equation

Given $64 = h^{2}$, taking the square root of both sides. By the property that if $x^{2}=a$ ($a\geq0$), then $x=\pm\sqrt{a}$. Here $a = 64$, so $h=\pm\sqrt{64}$.

Step2: Calculate the square - root value

Since $\sqrt{64}=8$, then $h = 8$ or $h=-8$.

Answer:

$h = 8$ or $h=-8$
