Kelas 9 Matematika
Bab 5 - Bilangan Berpangkat

Soal:
27^2/3 + (25/2018)^0 - (1/25)^-1/2 = ...?

Penyelesaian:
Bilangan berapa pun yg berpangkat 0 hasilnya 1.

27^2/3 + (25/2018)^0 - (1/25)^-1/2
= (3^3)^2/3 + 1 - (25/1)^1/2
= 3^3 × 2/3 + 1 - 25^1/2
= 3^2 + 1 - (5^2)^1/2
= 9 + 1 - 5^2 × 1/2
= 10 - 5^1
= 10 - 5
= 5

Jawaban:
5
