the sides of a square are five to the power of two fifths inches long. what is the area of the square? five to the power of four
mario62 [17]
The area of a square is given by;
Area=side^{2}
Area=5^{ \frac{2}{5} } * 5^{ \frac{2}{5} }
Basing on the law of indices;
a^{m} + a^{n}=a^{m+n}
so,
5^{ \frac{2}{5} } * 5^{ \frac{2}{5} } = 5^{ \frac{2}{5}+ \frac{2}{5}  } = 5^{ \frac{4}{5} }  square inches
