1963 TMTA High School Algebra I Contest Problem 9

Problem

Combine: $(-3)^4 - (-3)^3$

$\text{(A)} \quad (-3)^{7} \quad \text{(B)} \quad (-3)^{1} \quad \text{(C)} \quad 3^3\cdot 2^2 \quad \text{(D)} \quad 54 \quad \text{(E)} 3^1$

$(-3)^4 - (-3)^3 = (81) -(-27) = 108 = \boxed{\text{(C)} \quad 3^3 \cdot 2^2}$
