Question

Divide the following :
(i) 35x³yz² by -7xyz
(ii) -15x³yz³ by -5xyz²

Answer 1

(1) 35x³yz² by -7xyz
= (³⁵/_-7) x^{3 - 1}y^{1 - 1}z^{2 - 1} [Using quotient law x^m ÷ xⁿ = x^{m - n}]
= -5 x²y⁰z¹ [y⁰ = 1]
= -5x²z.
(2)
= (^-15/_-5) x^{3 - 1}y^{1 - 1}z^{3 - 2}. [Using quotient law x^m ÷ xⁿ = x^{m - n}].
= 3 x²y⁰z¹ [y⁰ = 1].
= 3x²z.
