What is the value of this expression: [tex]\left(\frac{1}{5}\right)^{-5}[/tex]?

A. 3125
B. \(\frac{1}{25}\)
C. 25
D. \(\frac{1}{3125}\)

Answer :

Final answer:

The value of 1/5 raised to the power of negative 5 is 3125. The negative exponent inverts the fraction before being raised to the positive value of that exponent. Thus, the answer is A. 3125.

Explanation:

The mathematical concept at work here is exponents, specifically, negative exponents. The expression in question is 1/5 raised to the power of negative 5. Raising a fraction to a negative exponent simply inverts the fraction and then raises it to the positive value of that exponent. In this case, 1/5 becomes 5/1, or simply '5'. Then, since our exponent is 5, we take '5' to the fifth power. Thus,

55 = 5 x 5 x 5 x 5 x 5 = 3125.

So, the value of 1/5 to the power of negative 5 is 3125. Hence, the answer is A. 3125.
