Question

If a number squared equals 49. Find the solution to x.

Answer 1

Answer:

x= 7

Step-by-step explanation:

Let the unknown number be x

${x}^{2} = 49$

Square root both sides

$\sqrt{ {x}^{2} } = \sqrt{49}$

Simplify

$x = 7$

Answer 2

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{x = 7}}}}}$

Step-by-step explanation:

Let the number be 'x'

Create an equation

$\sf{ {x}^{2} = 49}$

Squaring on both sides

$\dashrightarrow{ \sf{ \sqrt{ {x}^{2} } = \sqrt{49} }}$

$\dashrightarrow {\sf{ \: x = 7}}$

Hope I helped!
