Question

Which expression completes the statement to form a true equation?

2 + 4² =




A 2^5

B 9²

C 2³ + 9

D 3² + 9

Answer 1

2 + 4² = 2 + 16 = 18

A. 2⁵ = 2 · 2 · 2 · 2 · 2 = 32

B. 9² = 9 · 9 = 81

C. 2³ + 9 = 2 · 2 · 2 + 9 = 8 + 9 = 17

D. 3² + 9 = 3 · 3 + 9 = 9 + 9 = 18

Answer: D.

Answer 2

D

Explanation:

the value of the given expression is

2 + 4² = 2 + 16 = 18

Hence we require to find the expression which equals 18

A
`2^(5)` = 32 ≠ 18

B 9² = 81 ≠ 18

C 2³ + 9 = 8 + 9 = 17 ≠ 18

D 3² + 9 = 9 + 9 = 18 → D is the equivalent expression
