Question

(3²)³.5-²/15-¹=
Sya kurang faham tolong dijelaskan kak?

Answer 1

Jawaban:

437.4

Penjelasan dengan langkah-langkah:

hal yang harus diingatkan:

x^(-y)=1/(x^y)

(x^y)^z = x^yz

x^y • x^z = x^(y+z)

x^z • y^z= (xy)^z

(x^y)/(x^z)=x^(y-z)

(x^z)/(y^z)=(x/y)^z

jadi,

(3²)³ x 5^(-2)/15^(-1)

→ 3⁶ x 1/(5²)÷1/15

→ 729 x 1/25 ÷ 1/15

→ 729 x 1/25 x 15/1

→ 729 x 15/25

→ 729 x 3/5

→ 437.4

semoga membantu :D
