Question

Find the LCM of n^3t^2 and nt^4.
a) n^4t^6
b) n^3t^6
c) n^3t^4
d) nt^2

Answer 1

look at the variables independently.

The first term has n^3 and the second term has n^1 (or just n). What's the common multiple for those two?

The first term has t^2 and the second term has t^4. What's the common multiple for those two?
