Simplify the expression sqrt(7! + 6!), where n! stands for n(n-1)(n-2) ... 2*1.
\(7!=5040\)
\(6!=720\)
\(7!+6!=5040+720=5760\)
\(5760=2*2*2*2*2*2*2*3*3*5\)
\(=2^6*3^2*2*3*5\)
\(\sqrt(5760)=24\sqrt(30)\)
That is the answer, 24*sqrt(30).
For some reason, I cannot get the LaTeX to work on square roots. Does anyone know why?
