The answer is C. 2/5
When we raise the quotient 4/25 to the power of 1/2, we raise both the numerator and the denominator to the power. Here, our numerator is 4, our denominator is 25. Therefore,
(4/25)^(1/2) = 4^(1/2)/25^(1/2).
This property of exponents is called the power of a quotient power, where the denominator is not equal to zero.
For the one-half power of a number, we can write it as the square root of the number:
(4/25)^(1/2) = sqrt(4) / sqrt(25) = 2/5
Therefore, (4/25)^(1/2) = 2/5
