The expressions 3/x + 5/y and 3/(8p^2r) + 5/(4p^2r) are algebraic expressions
The simplified expressions are (3y + 5x)/xy and 13/(4p^2r)
How to solve the rational expressions?
From the complete question (see attachment), we have:
3/x + 5/y
Take the LCM
3/x + 5/y = (3y + 5x)/xy
Also, we have:
3/(8p^2r) + 5/(4p^2r)
Take the LCM
3/(8p^2r) + 5/(4p^2r) = (3 + 10)/(4p^2r)
Evaluate the sum
3/(8p^2r) + 5/(4p^2r) = 13/(4p^2r)
Hence, the simplified expressions are (3y + 5x)/xy and 13/(4p^2r)
