Answer 1

a)

$10^x~.~10^{-3}~=~10^{\,x+(-3)}~=~\boxed{10^{x-3}}$

b)

$10^{x}:10^{-3}~=~\frac{10^x}{10^{-3}}~=~10^{x-(-3)}~=~\boxed{10^{x+3}}$

c)

$\left(10^{x}\right)^{-3}~=~10^{\,x~.~(-3)}~=~\boxed{10^{-3x}}~ou~\boxed{\frac{1}{10^{3x}}}$

d)

$2^x~.~2~=~2^x~.~2^1~=~\boxed{2^{x+1}}$

e)

$\frac{2}{2^x}~=~\frac{2^1}{2^x}~=~\boxed{2^{\,1-x}}$

f)

$\frac{2}{2^{-1}}~=~\frac{2^1}{2^{-1}}~=~2^{\,1-(-1)}~=~2^{\,1+1}~=~\boxed{2^2}$

g)

$8^x:8^{x-5}~=~\frac{8^x}{8^{x-5}}~=~8^{x-(x-5)}~=~8^{x-x+5}~=~\boxed{8^{5}}$
