Final answer:
Expression c. 22 (3 x 52 + 22) is equal to 632.
Step-by-step explanation:
To determine which expression is equal to 632, we can evaluate each expression and see which one gives us the desired result. Let's check each option:
a. 2 (3 x 5 + 2) = 2 (15 + 2) = 2 (17) = 34
b. 21 (3 x 55 - 216) = 21 (165 - 216) = 21 (-51) = -1071
c. 22 (3 x 52 + 22) = 22 (78 + 22) = 22 (100) = 2200
d. 22 (3 x 52 + 25) = 22 (78 + 25) = 22 (103) = 2266
Therefore, the correct expression that is equal to 632 is option c. 22 (3 x 52 + 22).
