Answer 3

Sure, I'll explain step by step how to evaluate the expression 125 * 5^-2:

Step 1: Calculate 5 raised to the power of -2. To do this, remember that a negative exponent indicates taking the reciprocal of the base raised to the positive exponent. In this case, 5^-2 is equal to 1 / 5^2.

Step 2: Calculate 5^2. 5^2 means 5 raised to the power of 2, which is 5 * 5 = 25.

Step 3: Calculate 1 / 25. Since 5^-2 is equal to 1 / 25, the result of this step is 1 / 25 = 0.04.

Step 4: Multiply 125 by 0.04. Finally, multiply 125 by 0.04 to get the final result: 125 * 0.04 = 5

So, 125 * 5^-2 is equal to 5.
