Roi,
a) 5⁴ = 5.5.5.5 = 625
b) (-5)⁴ = (-5).(-5).(-5).(-5) = 625
c) -5⁴ = - (5.5.5.5) = -625
d) (2/5)⁻¹ = 5/2
e) (3/4)⁻² = (4/3)² = (4.4/3.3) = 16/9
f) π⁰ = 1
g) (-5)⁰ = 1
h) -5⁰ = -(5)⁰ = -1
i) 0⁰ = 1
j) 6⁻² = (1/6)² = 1/36
2-)
a) 4² x 4⁵ x 4⁻⁷ x 4³ = 4 (²⁺⁵⁺⁽⁻⁷⁾⁺³) = 4³
b) (3²)³ = 3⁶
c) 2⁰ x 2² x 2³ x 2⁻⁶ x 2⁵ = 2 (⁰⁺²⁺³⁺⁽⁻⁶⁾⁺⁵) = 2⁴
d) 6¹² ÷ 6⁸ = 6 (¹²⁻⁸) = 6⁴
e) 3⁴ ÷ 3⁴ = 3 (⁴⁻⁴) = 3⁰ = 1
Thanks.. ;)
