which is true?
If x = y2, which of the following is true?

Answer:
Option A, [tex]\sqrt{x}=y[/tex]
Step-by-step explanation:
Step 1: Determine which expression is true
Option A
[tex]\sqrt{x}=y[/tex]
[tex](\sqrt{x})^2=(y)^2[/tex]
[tex]x = y^2[/tex]
We don't need to go any further. We were able to determine that option A was true by squaring both sides which got rid of the square root around x and gave y another power which produced y^2.
Answer: Option A, [tex]\sqrt{x}=y[/tex]
