Pr ! (A)
1. 3³ = 3x3x3 = 27
2. (-3) = (-3)x(-3)x(-3) = -27
3. ⅓ = ⅓x⅓x⅓ = 1/27
4. 0,3³ = 0,3x0,3x0,3 = 0,027
5. 3²x3³ = 3x3x3x3x3 = 3^5 = 243
---------------------------------------------------------------
1. (3³×3⁴) : 3^5 = 3^7 : 3^5 = 3² = 9
2. 7³ : (7² : 7^5) = 7³ = (7² - ^5)
= 7³ : 7^-3
= 7³ - (-³)
= 7^6
3. 8×(2^5:2^6) = 8×2^-1
= 2³×2^-1
=2³-(-¹)=2²
---------------------------------------------------------------
1.) (2³:2-²)×2^-7 = (2³-(²))²×2^-7
= (2^5)² × 2^-7
= 2^10 × 2^-7
= 2³
