Question

Tolong dibantu yaa...
a. 3x²y⁵ : x²y² : xy² =

b. 15p⁴q⁵r³ : (6p²qr³ : 2pqr )

c. ( 2a²bc² + 8a³b²c³ ) : 2abc =

d. (p³qr² + p²q²r³ - p⁵q³r² ) : p²qr²

Answer 1

A) 3x^(2 - 2 - 1) y^(5 - 2 - 2)
= 3x^(-1) y
= 3y/x

b) 15p^4q^5r^3 : (3pr^2)
= 5p^3 q^5 r

c) 2abc(ac + a^2bc^2) : 2abc = ac + a^2 b c^2

d) p^2 qr^2 (p + qr - p^3 q) : p^2 qr^2
= p + qr - p^3 q

^ = pangkat

Answer 2

A) 3 x^(2-2-1) y^(5-2-2)= 3 x^(-1) y = 3y/x
b) 15 p^4 q^5 r^3 : (3 p^(2-1) q^(1-1) r^(3-1)) = 15p^4 q^5 r^3 : 3 p r^2 = 5 p^(4-1) q^5 r^(3-2) = 5p^3 q^5 r
c) 2abc(ac+4a^2bc^2) / 2abc = ac+4a^2bc^2
d)p^2qr^2 ( p+qr-p^3q^2) / p^2 qr^2 = p+qr-p^3q^2
