Simplify r^7s^4s*r^3

$r^{7} \cdot s^{4} \cdot s \cdot r^{3}$

Multiply $r^{7}$ by $r^{3}$ by adding the exponents.

Move $r^{3}$ .

$r^{3} r^{7} \cdot s^{4} \cdot s$

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

$r^{3 + 7} \cdot s^{4} \cdot s$

Add $3$ and $7$ .

$r^{10} \cdot s^{4} \cdot s$

Multiply $s^{4}$ by $s$ by adding the exponents.

Move $s$ .

$r^{10} \cdot (s \cdot s^{4})$

Multiply $s$ by $s^{4}$ .

Raise $s$ to the power of $1$ .

$r^{10} \cdot (s^{1} s^{4})$

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

$r^{10} \cdot s^{1 + 4}$

Add $1$ and $4$ .

$r^{10} \cdot s^{5}$

$r^{10} s^{5}$
