kerjakan soal soal berikut dengan benar!​

Jawaban:1. Nyatakan ke dalam bentuk bilangan bulat berpangkat! - a. √125- 125 = 5 x 5 x 5 = 5³- √125 = √(5³) = 5^(3/2)- b. 9 / ⁴√243- 9 = 3²- 243 = 3 x 3 x 3 x 3 x 3 = 3⁵- ⁴√243 = ⁴√(3⁵) = 3^(5/4)- 9 / ⁴√243 = 3² / 3^(5/4) = 3^(2 - 5/4) = 3^(8/4 - 5/4) = 3^(3/4) 2. Nyatakan ke dalam bentuk akar! @Ara1412- a. 7^(3/5)- 7^(3/5) = ⁵√7³ = ⁵√(7 x 7 x 7) = ⁵√343- b. 128^(-1/3)- 128^(-1/3) = 1 / 128^(1/3)- 128 = 2 x 2 x 2 x 2 x 2 x 2 x 2 = 2⁷- 128^(1/3) = (2⁷)^(1/3) = 2^(7/3)- 1 / 128^(1/3) = 1 / 2^(7/3) = 1 / (2² * 2^(1/3)) = 1 / (4 * ³√2) Jadi, 1. a. 5^(3/2)b. 3^(3/4)2. a. ⁵√343b. 1 / (4 * ³√2)
