11³+11⁴-->11³(11⁰+11¹)-->11³(1+11)-->11³(12)


Sorry guys, but I don't really understand that concept. Do you know more about it?

thank you

Hi thegame12 ,

Welcome to GMATClub

\(11^3 + 11^4 = 1*11^3 + 11*11^3\)(One multiplied with any number gives the same number)

This can be further simplified by taking the common term outside.
We need to follow the ‎distributive law a·b+a·c = a·(b+c)‎

In this case the common term is 11^3 which if taken outside gives
\(1*11^3 + 11*11^3 = 11^3(1+11) = 11^3(12)\)

Hope that helps!

pushpitkc has explained it, but are there any specific things here that you're not comfortable with? For example, are you okay "seeing" 11⁰ as 1 (any non-zero number raised to the power of 0 is 1)?
