Question

Solve the equation. If necessary, round your answer to the nearest tenth.

Answer 1

Answer:

–14, 14

Step-by-step explanation:

x^2 = 196

x = $\sqrt{196}$

x = $\sqrt{4 * 49}$

x = $\sqrt{4}$ * $\sqrt{49}$

x = 2 * 7

x = 14

Answer 2

Hi there!

${x}^{2} = 196$

Take the root (and minus root).
$x = \sqrt{196} \: \: or \: \: x = - \sqrt{196}$
$x = 14 \: \: \: \: or \: \: x = - 14$
