Question

the square of a number equals 8times the number.find the number

Answer 1

Let x = the number.

Square of a number = x²

8 times the number = 8x

Therefore, the square of a number equals 8 times the number is:

$x^2=8x$

From this, let's solve for x.

$\begin{gathered} x^2=8x \\ \frac{x^2}{x}=\frac{8x}{x} \\ x=8 \end{gathered}$

Therefore, the number is 8.
