Question

Choose the correct simplification of 4^3 / 4^2

Answer 1

4

Answer 2

\[\LARGE {4^3\over 4^2}={4\cdot 4\cdot 4\over 4\cdot 4 }=\]
\[\LARGE {\cancel4\cdot \cancel4\cdot 4\over \cancel4\cdot \cancel 4 }=4\]

or you just can use the formula:
\[\LARGE {x^a\over x^b}=x^{a-b}\]
so
\[\LARGE {4^3\over 4^2}=4^{3-2}=4^1=4 \]
