Algebra Difficulty 1.7 Junior Find the answer

The value of $\sqrt{3^{3}+3^{3}+3^{3}}$ is what?

Your answer

A number or a short expression. Fractions can be typed as 3/2, and spacing doesn't matter.

Solution

Since $3^{3}=3 \times 3 \times 3=3 \times 9=27$ , then $\sqrt{3^{3}+3^{3}+3^{3}}=\sqrt{27+27+27}=\sqrt{81}=9$ .
