35 = 45 - n
think of it as money
45 dollars take away how many (n) = 35 dollars
45 - n =35
or you can subtract 45 from both sides
-n = 35-45
-n = -10
divide by -1 from both sides
n = 10

Answer:

Step-by-step explanation:

$(2^{3})^{3} = 2^{3*3}=2^{9}\\\\\\(\dfrac{4^{2}}{5^{3}})^{3} = \dfrac{(4^{2})^{3}}{(5^{3})^{3}}=\dfrac{4^{6}}{5^{9}}\\\\\dfrac{3^{6}}{3^{3}}=3^{6-3}=3^{3}\\\\\\a^{m}*a^{n}=a^{m+n}\\\\(a^{m})^{n}=a^{m*n}\\\\\dfrac{a^{m}}{a^{n}}=a^{m-n}$
