Question

The sides of a square are three to the power of two sevenths inches long. What is the area of the square?

A) nine to the power of four sevenths square inches
B) three to the power of four sevenths square inches
C) three to the power of the fraction four over forty nine square inches
D) nine to the power of the fraction four over forty nine square inches

Answer 1

( 3^(4/7) ) square inches

Explanation:

So you say that the length of each side of this square is 3^(2/7) inches. What's the area of the square? Use the formula A = s^2, which applies to squares of side length s.

Then, in this case, A = ( 3^(2/7) ^2. This simplifies to A = ( 3^(4/7) ) square inches (Answer B)
