Hi,
Re:  TY
{{{a^4b^1 + a^2b^3 = a^2a^2b + a^2b^2b^1}}}  | Note: {{{ x^(m+n) = ( x^m )( x^n ) }}} 
then factored out common terms a^2b^1 to get {{{a^2b(a^2 + b^2)}}}
If You meant:
a^4b + a^2b^3    |note the use of the ^ (uppercase 6)
{{{a^2b(a^2 + b^2)}}}
_____________________________________________________
{{{a^0 = 1}}}
{{{a^1 = a}}} ****
{{{(a^p)^q = a^(p*q)}}}
{{{root(a,p)*root(a,q) = root(a,p*q)}}}
{{{x^m/x^n=x^(m-n)}}}
{{{( x^m )( x^n ) = x^( m + n )}}}    *********
