Question

(-3)^-3×(-3)^-2×(-3)^-5

Answer 1

Answer:

Step-by-step explanation:

$(-3)^{-3}* (-3)^{-2}* (-3)^{-5}$

$(-3)^{(-3)+(-2)+(-5)}$  ---- since $a^{m} *a^{n} *a^{p} = a^{m+n+p}$

$(-3)^{(-3-2-5)}$

$(-3)^{(-10)}$

$\frac{-1}{3^{10} }$  ---- since $a^{-1} = \frac{a}{a} \\a^{-10} =\frac{1}{a^{10} }$

$\frac{(-1)^{10} }{(3)^{10} }$

$\frac{1}{3^{10} }$
