Ответ:
x^2 = 100/4
x^2 = 25take the sqrt of both sides, eliminating the ^2
x = sqrt 25
x = 5 <===
Ответ:
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
