Sederhanakan perpangkatan berikut ini. c. 4(−2,5)⁴ × (−2,5)³

Jawabnya adalah -(5^(7))/(2^(5)) Ingat (ab)^m = a^m x b^m (a/b)^m = a^m / b^m (-1)^m = -1 jika m bilangan ganjil (-1)^m = 1, jika m bilangan genap a^m x a^n = a^(m+n) 1/(a^m) = a^(-m) 4x (−2,5)⁴ x (−2,5)³ = 2²x(-1⁴x 25⁴ / 10⁴) x (-1³ x 25³ /10³) = 2²x(1x 25⁴ x10^(-4)) x (-1 x 25³ x10^(-3)) = -1 x 2²x( (5²)⁴ x(2x5)^(-4) x ((5²)³ x(2x5)^(-3)) =-1 x 2² x (5^(8)x 2^(-4) x 5^(-4)) x ( 5^(6) x 2^(-3)x5^(-3)) = -1 x 2² x (5^(8-4)x 2^(-4) ) x ( 5^(6-3) x 2^(-3)) = -1 x 2² x (5^(4)x 2^(-4)) x ( 5^(3) x 2^(-3)) = -1 x 2^(2-4-3) x 5^(4+3) = -1 x 2^(-5) x 5^(7) = -(5^(7))/(2^(5)) Jadi Jawabannya adalah -(5^(7))/(2^(5))
