Question

Sederhanakan bentuk perpangkatan berikut:
1. 2x^3 . 7x^4 . (3x)^2
2. (-2p/q) x (-q)^4 x 2/5 x p^2
3. y^5 . (x.y)^3 . (1/x^2.y)

Answer 1

1. 2x^3 . 7x^4 . (3x)^2
= 2^3 .7^4 . 9^2
= 126 ^9
2. (-2p/q) x (-q)^4 x 2/5 x p^2
= (-2p/q) . (-q)^4 . 2/5 p^2
= (-2p )^1 . 2/5 p^2 . (1/q .(-q)^4)
= -4/5 ^3 . (-q^4 / q )
= -4/5 ^3 . (-q^3 )
= 4/5 ( p . q)^3
3. y^5 . (x.y)^3 . (1/x^2.y)
=y^5 . x^3 . y^3 .y/x^2
= x^3-2 . y^5+3+1
= x.^9
