A side of a square is A = 8^(3/2) inches. Using the area formula A = s2, determine the area of the square.?A = 24 square inches

VLD [36.1K]

Answer:

512 square inches

Step-by-step explanation:

If A = s², and $s=8^{\frac{3}{2}}$ , then

$A=s^2=(8^{\frac{3}{2}})^2$ and

$A=s^2=8^{\frac{6}{2}}$ which simplifies to

$A=s^2=8^3$ which simplifies to

$A=s^2=512$

Therefore, if $A=s^2$ and $s^2=512$ , then

A = 512 square inches
