4x^2 = 100...divide both sides by 4
x^2 = 100/4
x^2 = 25....take the sqrt of both sides, eliminating the ^2
x = sqrt 25
x = 5 <===

4x²=100

Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.

Divide 4 from both sides

(4x²)/4 = (100)/4

x² = 25

Root both sides to isolate the x

√x² = √25

x = √25

x = 5

5 is your answer

hope this helps
