Answer 2

Answer:

The answer is -

Step-by-step explanation:

To evaluate $(-3)^{-4}$ [iv] and $(-2/3)^{-5}$ [v]

Follow the basic rules and laws of exponents

$(-3)^{-4}$

First convert the negative exponent to positive exponent

As we know that to make the negative exponent to positive exponent we do the reciprocal of the base (-3)

base =  (-3)

exponent = -4

Reciprocal of the base = (-1/3)

So,

$(-3)^{-4}$ = $(\frac{-1}{3})^{4}$

$(-3)^{-4}$ = $\frac{-1 X -1 X -1 X -1}{3 X 3 X 3 X 3}$

$(-3)^{-4}$ = 1/81

AND,

$(-2/3)^{-5}$ = $(\frac{-2}{3})^{-5}$

First convert the negative exponent to positive exponent

As we know that to make the negative exponent to positive exponent we do the reciprocal of the base (-2/3)

base =  (-2/3)

exponent = -5

Reciprocal of the base = (-3/2)

So,

              = $(\frac{-3}{2})^{5}$

              = $\frac{-3 X -3 X -3 X -3 X -3}{2 X 2 X 2 X 2 X 2}$

              = $\frac{9 X -27}{4 X 8}$

$(-2/3)^{-5}$ = -243/32
