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.
