Write each of the following in expanded form.

$z^3{y}^4$

STEP 1:

$a^n$ read as a raised to the power of$n$, where $n$ is the exponent or index and $a$ is the base.

The expanded form of$a^n=a\times a\times a\times a....ntimes$.

thus, the expanded form of$z^3{y}^4$,

$z^3{y}^4=z\times z\times z\times y\times y\times y\times y$
