QuizQ2

The square of the first number is equal to three-fifths of the second number. Determine both numbers if you know that the second number is 5 times greater than the first, and neither of numbers is not equal to zero.

Correct result:

a =  3
b =  15

Solution:

$a^2 = \dfrac35 b \ \\ b = 5a \ \\ \ \\ a^2 = \dfrac35 5a \ \\ a^2 = 3a \ \\ a = 3 \ \\ b = 5a = 15$
