Answer 1

Answer:

$=15( {a}^{46} {b}^{36} )$

Step-by-step explanation:

$3( {a}^{4} {b}^{3} )^{10} \times 5( {a}^{2} {b}^{2} ) ^{3} \\ 3 \times {a}^{40} \times {b}^{30} \times 5 \times {a}^{6} \times {b}^{6} \\ 15 \times {a}^{40} \times {a}^{6} \times {b}^{30} \times {b}^{6} \\ 15 \times {a}^{40 + 6} \times {b}^{30 + 6} \\ 15 {a}^{46} {b}^{36}$
