A.5^7×5^3
B.8(-2,5)^4x(-2,5)^3
2.sederhanakan perpangkatan berikut ini.
((2+5-3)^2)^3
1.sederhanakan perpangkatan berikut ini.
Jawab:
1. a. 5⁷ x 5³ = 5⁷⁺³ = 5¹⁰ = 9.765.625
b. 8.(-2,5)⁴ x (-2,5)³ = 8(-2,5)⁴⁺³ = 8(-2,5)⁷ = 8.-610,3515625 = -4882,8125
2. ((2+5-3)²)³ = (2+5-3)²ˣ³ = (2+5-3)⁶ = 2⁶ + 5⁶ – 3⁶ = 64 + 15.625 – 729 = 14.960
