Answer:

1) 32 $m^{6}$ $n^{14}$

2) 3 $j^{4}$ $k^{8}$

3) 135 $a^{11}$ $b^{16}$

Step-by-step explanation:

to know: when multiplying terms with same base and exponents, multiply the bases and add the exponents

to know: when dividing terms with same base and exponents, divide the bases and subtract the exponents

to know: whenever exponents are contained within a set of parentheses and separated by another set of parentheses, multiply the exponents

1) ( $4^{4}$ · $m^{12}$ · $n^{20}$ ) ÷ 2³ $m^{6}$ $n^{6}$ = 3 $j^{4}$ $k^{8}$

2) (15 $j^{5}$ $k^{2}$ · 25j² $k^{9}$ ) ÷ 5³j³k³ = (375 $j^{7}$ $k^{11}$ ) ÷ 125j³k³ = 3 $j^{4}$ $k^{8}$

3) (5 · 3³) $a^{11}$ $b^{16}$ = 135 $a^{11}$ $b^{16}$
