Answer 1

Answer:n=3

Step-by-step explanation:5*2nx5*3=5*9

5*2n=5*9/5*3

5*2n=5*6

2n=6

n=3

Answer 2

$\bold{part \: 1}$

${5}^{2n} \times {5}^{ 3} = {5}^{9}$
${5}^{2n + 3} = 5 {}^{9}$
2n+3=9
2n=6
$\boxed{n = 3}$
$\bold{part \: 2}$
${8} \times {2}^{2n + 2} \: = 32$
${2}^{3} \times {2}^{2n + 2} = {2}^{5}$
${2}^{3 + 2n + 2} = {2}^{5}$
3+2n+2=5
2n=5-5
2n=0
$\boxed{n = 0}$
