What is the least common denominator of 4x2 y 5y2 xy xy2 x

What is the least common denominator of 4/x^2 y + 5/y^2 ? xy xy^2 x^2y^2 x^2y What is the least common denominator of the expression a/5 + a/x + 5? x + 5 5(x + 5) 5a a(x + 5)

Solution

1. To find the least common denominator we need to find a term which makes the denominator of two terms equal

In this case, for x²y and y² we need to make them same which can be done by multiplying

(x²y)(y) = x²y²

(y²)(x²) = x²y²

So the least common denominator for the expression is x²y²

2. Now applying same concept here, we\'ll get least common denominator 5(x+5)
