Question

the product of two rational number is 7260. if one number is 15 times the other number find the number

Answer 1

Answer:

Step-by-step explanation:

Let one number be 'x'. So other number is '15x'

X × 15x = 7260

xsq. = 7260/15

x = sq.root of 414

Answer 2

Answer:

1. 22
2. 330

Step-by-step explanation:

Let, the first no. = a

Then, 2nd no. =15a

According to the question,

a ☓ 15a = 7260

$15 {a}^{2} \: = 7260 \\ {a \: }^{2} \: \: \: \: = \: 7260 \div 15 \\ {a }^{2} \: \: \: \: \: = 484 \\ \sqrt{a^{2} } \: = \sqrt{484 } \\ a \: \: \: \: \: \: = 22$

The first number = a = 22

The second number = 15a = 15 ☓ 22

=330
