Question

LCD for 13/4x and 27/3x^2

Answer 1

`(13)/(4x) , (27)/(3 x^(2) )`

In the least common denominator, LCD, we consider the terms that are in the denominator of the fractions; therefore in this case, our focus will be on:

`4x,3x^(2)`

Now,
Let us find LCD of the above two terms:

`4x` = 2*2*
`x`

`3x^(2)` = 3*
`x^(2)`

Therefore, the LCD = 2*2*3*
`x^(2)` (always go for the highest level exponent for LCD)

Ans: LCD = 12
`x^(2)`
