Question

Find the lowest common denominator of 3/x^3y and 7/xy^4 . A. x3y4 B. x2y3 C. x4y5 D. xy4

Answer 1

the correct answer is A; x^3 and y^4 good luck and hoped this helped 

Answer 2

The answer is the option A

`x^(3)y^(4)`

Explanation:

we know that

The lowest common denominator it is the smallest positive integer that is a multiple of each denominator in the set

In this problem we have

`(3)/(x^(3)y)` and
`(7)/(xy^(4))`

so

between

`x^(3)y` and
`xy^(4)`

the lowest common denominator is equal to

`x^(3)y^(4)`
