a) 2⁻⁵ ⋅ 2⁶ = 2^(-5+6) = 2¹ = 2
б) 3⁻⁶ ⋅ 3⁵ = 3^(-6+5) = 3⁻¹ = 1/3
в) 7⁻² ⋅ 7⁰ = 7^(-2+0) = 7⁻² = 1/49
г) 5³ : 5⁵ = 5^(3-5) = 5⁻² = 1/25
д) 6⁻² : 6⁻⁴ = 6^(-2-(-4)) = 6² = 36
е) 10³ : 10⁻¹ = 10^(3-(-1)) = 10⁴ = 10000
ж) (3⁻²)² = 3^(-2*2) = 3⁻⁴ = 1/81
з) (5²)⁻¹ = 5^(2*(-1)) = 5⁻² = 1/25
и) (10⁻²)⁻³ = 10^(-2*(-3)) = 10⁶ = 1000000
