Find the smallest positive integer k such that 3240/k is a square number

10

Step-by-step explanation:

First, factorize the number 3,240:

So,

Now consider the fraction

If k = 10, then

is a square number.

For all k < 10, the fraction tex]\dfrac{3,240}{k}[/tex] is not a square number (this follows from factorization).

Or you can simply check the values of the fraction for all k < 10:

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

step-by-step explanation: the answer is 27. first multiply .32 by 25 which equals 8. then add 8 to 25 which gives you 33. then you subtract that from 6 since she gave 6 to her brother.
