Question

What is the LCD of (5)/(7x^3y^7) and (1)/(4x^4y^5)

Answer 1

7x^3y^7 = 7*x*x*x*y*y*y*y*y*y*y
4x^4y^5 = 2*2*x*x*x*x*y*y*y*y*y

Answer 2

Now, LCM = 7*4*x^4*y^7

Answer 3

got it?

Answer 4

Alright..

Answer 5

LCD of (5)/(7x^3y^7) and (1)/(4x^4y^5) = LCM of 7x^3y^7 and 4x^4y^5

Answer 6

Alright.
