3(sqrt7t)((2(sqrt7t) + 3(sqrt3t^2))
:
%283%2Asqrt%287t%29%29 *%282%2Asqrt%287t%29+%2B+3%2Asqrt%283t%5E2%29%29
:
Multiply both terms inside the brackets by %283%2Asqrt%287t%29%29; results:
6(7t) + 9%2Asqrt%2821t%5E3%29%29
or
6(7t) + 9%2Asqrt%2821t%5E2%2At%29%29
Extract the square root of t^2
42t + 9t%2Asqrt%2821t%29%29
:
Factor out 3t
:
3t%2814+%2B+3%2Asqrt%2821t%29%29
