Sstrechkova N.P.

Nезнayka (which translates to "Don't-know" in English) does not know about the operations of multiplication and exponentiation. However, he has well mastered addition, subtraction, division, and square root extraction, and he also knows how to use parentheses.

Practicing, Nезнayka chose three numbers 20, 2, and 2 and formed the expression $\$ \backslash q r t\{(2+20): 2\} \$$ (which translates to $\sqrt{(2+20) / 2}$). Can he, using exactly the same three numbers 20, 2, and 2, form an expression whose value is greater than 30?
$\$|frac{20}{2-\\ sqrt{2}}=| frac{20(2+\\ operatorname{sqrt}{2})}{2}=20+10 \\$ sqrt ${2}>20+10 . \\$ There are other solutions.

## Answer

It can.
