Question

The product of two numbers is 1296. If one number is 16 times the others find the numbers.

Answer 1

Product of two numbers = 1296
Let one number = x
Second number = 16x
$\therefore 16x\times x=1296$
$\Rightarrow 16x^2=1296$
$x^2=\frac{1296}{16}=81=(9{)}^2$
$\therefore x=9$
$\therefore$ First number = 9
and second number = $16\times 9=144$
