Could you tell me how this equation works and how to get to the answer.ive done it before and am still stuck on how 6a^2b^2 is in the middle(adsbygoogle = window.adsbygoogle || []).push({});

(a+b)^4

a^4 4a^3b

giving the 6A^2B^2 in the middle is it if you have a exponent out side the brackets it works down to ^2 as it would look like or is there an easyer way to say how to do this equation.

is there a formula to work it out.
