From Examples 6-8, it is known that even powers of a variable are perfect square factors of the variable. Therefore, what must be true about the power of any
variable left in the radicand of a simplified square root? Explain.
Choose the correct answer below.
OA. The power of any variable left in the radicand of a simplified square root would be one, since the smallest even number greater than the exponent would be
a perfect square which would be factored out of the radical. So the leftover would be the variable raised to the exponent one.
B. The power of any variable left in the radicand of a simplified square root would be one, since the largest even number less than the exponent would be a
perfect square which would be factored out of the radical. So the leftover would be the variable raised to the exponent one.
OC.
The power of any variable left in the radicand of a simplified square root would be two, since the smallest even number greater than the exponent would be
a perfect square which would be factored out of the radical. So the leftover would be the variable raised to the exponent two.
