If x^c and x^e are denominators of two fractions and c>e, then x^c is the LCD.

I say that it is false, but not completely sure. Can you please help?
 
what is the LCD of the two fractions \(\displaystyle \L \frac{a}{x^3}\) and \(\displaystyle \L \frac{b}{x^2}\) ?
 
Intermediate Algebra

Skeeter, You asked what the LCD was for the two fractions:
a
-----
x^3
and
b
----
x^2

I think that it is 6. Is that correct?


Thank you for your help!

Skeeter, LCD means Least Common Denominator. 2 and 3 both go into 6.
What am I doing wrong?
Thank you.

Click to expand...
Because \(\displaystyle \L \frac{{x^3 }}{{x^2 }} = x\) then \(\displaystyle \L x^3\) is the LCD.
