a) 32
b) 402
c) 28
d) 422

Answer 1

The expression 2+ 2^2/25 × (5)^5 evaluates to 502 when calculated step by step, which is not listed among the provided options a) 32, b) 402, c) 28, d) 422.

Step-by-step explanation:

To evaluate the expression 2 + 2^2/25 × (5)^5 for s=2 and t=5, we begin by substituting the given values for s and t into the expression. However, the expression appears to have been presented ambiguously, and it seems there are no variables 's' and 't' to substitute, so we will evaluate the expression as is.

First, let's calculate the power and multiplication part of the expression:

1. (2^2) equals 4.
2. (5^5) equals 3125.
3. (4/25) equals 0.16.
4. (0.16) × (3125) equals 500.

Now let's add the initial 2 to the product:

• 2 + 500 equals 502.

This means the value of the given expression is 502.
