Question

the product of two numbers is 1296. if one number is 4 times the other , find the two numbers​

Answer 1

Answer:

Let the number be x and 4x

$4x \times x = 4 {x}^{2} \\ according \: to \: the \: question \\ 4 {x}^{2} = 1296 \\ {x}^{2} = \frac{1296}{4} \\ {x}^{2} = 324 \\ x \: = \sqrt{324 } \\ x \: = 18 \\ so \: the \: numbers \: are \: 18 \: and \: 72$
