a) 1/4^2 = 4^-2
b) 4^-3/4^-2 = 4^(-3-(-2)) = 4^(-3+2) = 4^-1
c) (1/4)^-4 = (1)^-4/(4)^-4 = 1/4^-4 = 4^4
d) 1/0.25^2 = 0.25^-2 = 16 = 4^2
bonjour
a) 1 /4 ² = 1 /16 = 4 ⁻²
b. 4 ⁻³ : 4 ⁻² = 4 ⁻¹
c. ( 1/4 ) ⁻⁴ = 4 ⁴
d. 1 /0.25² = 1/ 16 = 4 ⁻²
5 ⁻¹ x ( 5 ³)² = 5 ⁻¹ x 5 ⁶ = 5 ⁵
9² x 3 ⁻³ x 81 = ( 3²)² x 3 ⁻³ x 3 ⁴ = 3 ⁴ x 3 ⁻³ x 3 ⁴ = 3 ⁵
1/10 ² = 10 ⁻²
1/0.01 ² = 10⁴
0.01 / 100 = 10 ⁻² : 10 ² = 10 ⁻⁴
100 ³ : 0.01 ⁻³ = 10 ⁶ : 10 ⁶ = 10 ⁰ = 1
( 100/ 0.1) ³ = 10 ⁹
