Done
Decimal Form: -0.5
Answer: D.)
Step-by-step explanation:
The first step would be to reduce the fraction in the square root, so divide both the numerator and denominator by 25 to get 1/4.
Then calculate the root, any root of one equals one so that stays as is. The exponential form of 4 would be 2^2.
Then reduce the index of the radical and exponent with 2 and you get answer D
