a) 2 ⁻³ = 1 / 2 ³ = 1 /8
b) ( - 5 ) ⁻⁴ = 1 / ( - 5 )⁴ = 1/625
c) 3 ⁻² = 1 /3 ² = 1/9
d) 7 ⁻¹ = 1 /7
e) 10 ⁻³ = 1 /10 ³ = 1 /1000
f) - 5 ⁻⁴ = - 1/5 ⁴ = - 1/625
g ) ( 3/4 ) ⁻² = 1 / ( 3/4 )² = 4/3
h ) ( - 1/2) ⁻³ = ( - 1 /1/2)³ = - 5
i ) ( 9/5 ) ⁻⁴ = 1 / ( 9/5 ) ⁴
m ) 9 ⁻⁴ /5 = 5 / 9 ⁴
p = - 1 /2 ⁻³ = - 1 * 1 /2 ³ = - 1 * 8 = - 8
