solve plz
(a+b)^7
Remember, GL.....we can distribute an exponent over this (a * b)7.......but not this (a + b)7
The second thing says to multiply (a + b) seven times......
$${\left({\mathtt{a}}{\mathtt{\,\small\textbf+\,}}{\mathtt{b}}\right)}^{{\mathtt{7}}}$$
Distribute.
$${{\mathtt{a}}}^{{\mathtt{7}}}{\mathtt{\,\small\textbf+\,}}{{\mathtt{b}}}^{{\mathtt{7}}}$$
That's as far as can be simplified, I'm afraid.
And then there's CPhill...
