Best ResponseYou've already chosen the best response.0what's the LCM of 14 and 21

Best ResponseYou've already chosen the best response.2for the coefficent  LCM multiply the coefficient  what is the smallest number that both 14 and 21 divide evenly. So look at x^3 and x^5; Do you see that x^5 is the smallest monomial that both x^3 and x^5 divide evenly?  And looking at b^7 and b^2; Do you see that b^7 is the smallest?

Best ResponseYou've already chosen the best response.0you just take the larger exponent so the LCM is a^5

Best ResponseYou've already chosen the best response.0here is what I have 7a^8b^9 249a^8b^9 249a^3b^2 7a^3b^2

Best ResponseYou've already chosen the best response.0looks like you want the GCF (and not the LCM) then

Best ResponseYou've already chosen the best response.0I see the GCF in there, but not the LCM

Best ResponseYou've already chosen the best response.2your answer for the 7 is correct, but for GCF and exponents; you take the smaller of the exponents
