Is this correct? LCD of rational expressions

OpenStudy (quickstudent):

OpenStudy (shiburinga):

I think so.

OpenStudy (shiburinga):

Do you want me to get a Qualified Helper?

OpenStudy (quickstudent):

No thanks. I can wait. :)

TheSmartOne (thesmartone):

It's wrong :P

OpenStudy (solomonzelman):

\(\large\color{#000000 }{ \displaystyle 5x^2=5\cdot x\cdot x }\) \(\large\color{#000000 }{ \displaystyle 15x=5\cdot 3\cdot x }\) yes, your answer is wrong

OpenStudy (quickstudent):

I thought so:(

OpenStudy (solomonzelman):

The least common denominator, has to be divisible by both 5x^2 and 15x.

TheSmartOne (thesmartone):

^

TheSmartOne (thesmartone):

So, first we look at what is the least common multiple of 5 and 15 and the lcm of x and x^2

OpenStudy (quickstudent):

LCM of 5 and 15 is 15, and LCM of x and x^2 is x^2

TheSmartOne (thesmartone):

so the lcm of 5x^2 and 15x will be 15x^2 :D

OpenStudy (quickstudent):

:D Thanks!

TheSmartOne (thesmartone):

Anytime! :D
