Answer:
n = 10 and n = 16
Step-by-step explanation:
Using the rules of exponents
[tex]a^{m}[/tex] × [tex]a^{n}[/tex] = [tex]a^{(m+n)}[/tex] , then
[tex]4^{8}[/tex] × 4² = [tex]4^{(8+2)}[/tex]
= [tex]4^{10}[/tex] , thus n = 10
---------------------------------------------
[tex](a^m)^{n}[/tex] = [tex]a^{mn}[/tex] , then
[tex](3^2)^{8}[/tex]
= [tex]3^{2(8)}[/tex]
= [tex]3^{16}[/tex] , thus n = 16

SOMEONE HELP PLEASE!!!
Answer:
x = 2 1/3
y = 14 / (2 1/3) = 14 / (7/3) = 14*3/7 = 42/7 = 6
y = 6
x = 4 1/5
y = 14 / (4 1/5) = 14 / (21/5) = 14*5/21 = 70/21 = 3 7/21 = 3 1/3
y = 3 1/3
x = 7/6
y = 14 / (7/6) = 14*6 / 7 = 12
y = 12
