Q1 Find the value of
Solve c,b,d

Answer 1

Answer:

a^-1 = 1/a

Step-by-step explanation:

(b)

(3^-2 - 5^-3)÷ 4^-2

= (1/3 ^2 - 1/5^3) ÷ 1/4^2

= (1/9 - 1/125) ÷ 1/16

LCM ( 9,125) =1125

=(( 125 -9 )/1125 ) ÷ 1/16

= (116 /1125) ÷ 1/16

=( 116/1125 ) * 16

= (116 * 16)/1125

= 1856/1125

Answer 2

Answer:

d)=729/4096

Step-by-step explanation:

[(-3/4)^-3]^-2

=(-3/4)^-3×-2

=(-3/4)^6

=(-3)×(-3)×(-3)×(-3)×(-3)×(-3)/4×4×4×4×4×4

=729/4096
