25 + 27 = ?
Hl
To find the value of the expression r^2 + s^3 when r = 5 and s = 3, you need to substitute the given values of r and s into the expression and perform the operations.
Step 1: Substitute the values of r and s into the expression:
r^2 + s^3 = 5^2 + 3^3
Step 2: Perform the exponentiation operation:
5^2 = 5 * 5 = 25
3^3 = 3 * 3 * 3 = 27
Step 3: Perform the addition operation:
25 + 27 = 52
Therefore, when r = 5 and s = 3, the value of the expression r^2 + s^3 is 52.
