$r^29 t^32$

$(r^3t^4)^3 (r^4t^4)^5$

Remove the brackets by multiplying the indices.

$r^9t^12 xx r^20 t^20$

To multiply, add the indices of like bases:

$r^29 t^32$

How do you multiply (r ^ { 3} t ^ { 4} ) ^ { 3} ( r ^ { 4} t ^ { 4} ) ^ { 5}(r ^ { 3} t ^ { 4} ) ^ { 3} ( r ^ { 4} t ^ { 4} ) ^ { 5}?
