Solve the following exercise:
Solve the following exercise:
Simplify the following expression:
Begin by reducing the fraction under the square root:
Apply two exponent laws:
A. Definition of root as a power:
B. The power law for powers applied to terms in parentheses:
Let's return to the expression that we obtained. Apply the law mentioned in A and convert the square root to a power:
Next use the power law mentioned in B, apply the power separately to the numerator and denominator.
In the next step remember that raising the number 1 to any power will always result in 1.
In the fraction's denominator we'll return to the root notation, again, using the power law mentioned in A (in the opposite direction):
Let's summarize the simplification of the given expression:
Therefore, the correct answer is answer D.
