Question

Calcule??????????????????

Answer 1

$a)\\\\\frac{4^5}{4^3}~~=~~4^{\,5-3}~~=~~4^2~~=~~\boxed{16}\\\\\\b)\\\\\frac{-4^5}{4^3}~~=~~-\frac{4^5}{4^3}~~=~~-4^{\,5-3}~~=~~-4^2~~=~~\boxed{-16}\\\\\\c)\\\\\frac{-4^5}{-4^3}~~=~~\frac{4^5}{4^3}~~=~~4^{\,5-3}~~=~~4^2~~=~~\boxed{16}\\\\\\d)\\\\\frac{\left(4^2\right)^3}{4^5}~~=~~\frac{4^{\,2~.~3}}{4^5}~~=~~\frac{4^6}{4^5}~~=~~4^{6-5}~~=~~4^1~~=~~\boxed{4}$
