nilai dari 1 per 125 pangkat 1 per 3 + 1/81 pangkat 3/4 + 8 pangkat 2/3 adalah

Kelas 9 Matematika
Bab Akar dan Pangkat

^ = pangkat

(1/125)^(1/3) + (1/81)^(3/4) + 8^(2/3)
= (5⁻³)^(1/3) + (3⁻⁴)^(3/4) + (2³)^(2/3)
= 5⁻¹ + 3⁻³ + 2²
= 1/5 + 1/27 + 4
= (27 + 5)/(27 . 5) + 4
= 4  32/135

(1/125)^(1/3) + (1/81)^(3/4) + 8^(2/3)
= 5^(-3 . 1/3) + 3^(-4 . 3/4) + 2^(3 . 2/3)
= 5^(-1) + 3^(-3) + 2^(2)
= 1/5 + 1/27 + 4
= 27/135 + 5/135 + 540/135
= 572/135
= 4 32/135
