Question

The product of two numbers is 1296 if one number is 16 times the other. find the number?

Answer 1

Given the product of two numbers = 1296
Also given that , one number is 16 times the other number 
Let the other number be 'x' .
16 times of that number = 16×x = 16x 
Now , Product of two numbers = 1296
       ⇒x×16x = 1296
       ⇒16x² = 1296
       ⇒ x² = 1296/16 
       ⇒ x² = 81 
       ⇒ x = √81 = 9 
Therefore , the numbers are (x) = 9 ,
                                           (16x) = 16 × 9 = 144

Answer 2

x×16x=1296
16xsquare= 1296÷16
=81
x square= 20.5
