hitunglah (a) 125 ^2/3 - 81 3/4 (b) 9 1/2 + 125 2/3 (c) 8 2/3 +16 1/4

SEMUA BILANGAN HARUS DIJADIKAN DALAM BENTUK YG PALING SEDERHANA. Contoh: 25 dijadikan 5^2

(a)
125^(2/3) - 81^(3/4)
= 5^3(2/3) - 3^4(3/4)
= 5^2 - 3^3
= 25 - 27
= -2

(b)
9^1/2 + 125^2/3
= 3^2(1/2) + 5^3(2/3)
= 3^1 + 5^2
= 28

(c)
8^2/3 + 16^1/4
= 2^3(2/3) + 2^4(1/4)
= 2^2 + 2^1
= 6

Mohon koreksinya. Hope it helps, have a good night!
