Answer 1

I. ( 3/5)^-1

= (5/3)

ii. ( -2/3) ^-5

=-243/ 32

iii. we can write

( -4/3)^3 ÷ ( -3/4)^-7

= ( -4/3)^3 × ( -4/3)^-7

= ( -4/3) ^-4

= ( -3/4)^4

= 81/256

=

Answer 2

Answer:

i)

$\frac{3}{5}$

ii)

$\frac{32}{243}$

iii)

$\frac{81}{256}$

Step-by-step explanation:

i)

$\frac{3}{5}^{ - 4 + 3} = \frac{3}{5}$

ii)

$\frac{ - 2}{3}^{ - 2 - 3} \\ \frac{ - 2}{3}^{ - 5} = \frac{ - 32}{ - 243} = \frac{32}{243}$

iii)

$\frac{ - 3}{4}^{ - 3 - ( - 7)} \\ = \frac{ - 3}{4}^{4} \\ = \frac{81}{256}$
