Question

HELPPPPP please its worth 50

Answer 1

$(3 {m}^{6} {n}^{2} ) ^{3} .2m {n}^{4} \\ = {3}^{3} {m}^{6 \times 3} {n}^{2 \times 3} \times 2 m{n}^{4} \\ = 27 {m}^{18} {n}^{6} \times 2m {n}^{4} \\ = (27 \times 2) {m}^{18 + 1} {n}^{6 + 4} \\ = 54 {m}^{19} {n}^{10}$

Answer:

$54 {m}^{19} {n}^{10}$

Hope you could get an idea from here.

Doubt clarification - use comment section.

Answer 2

Answer:

Solution given:

$\bold{(3m^6n²)³.2mn⁴}$

distribute power

$3³m^{6*3}n^{2*3}.2mn⁴$

$27m^{18}n^6.2mn⁴$

multiply like terms and add or subtract power in multiplication

$27*2.m^{18+1}n^{6+4}$

$\large{\bold{54m^{18}n^{10}}}$ is a required answer
