Question

Find the least common denominator for these two rational expressions for 4/a^2 3/7a

Answer 1

The least common denominator for these two rational expression is

=7
`a^(2)`

Explanation:

• The two rational expressions are

• 
  `(4)/(a^2)`
  `(3)/(7a)`

• finding the least common denominator, we take L.C.M

• 
  `(4)/(a^2)`
  `(3)/(7a)`

The L.C.M is 7

Therefore, the largest number is
`a^(2)`

The least common denominator for these two rational expression is

=7
`a^(2)`
