what is the square root of 94 + 20
$$\sqrt{94}+20$$
can't be simplified
$${\mathtt{94}}{\mathtt{\,\small\textbf+\,}}{\mathtt{20}} = {\mathtt{114}}$$
$${\sqrt{{\mathtt{114}}}} = {\mathtt{10.677\: \!078\: \!252\: \!031\: \!311\: \!2}}$$
You will probably have to estimate, but there is the answer if you want it.
