If x is a positive integer, for how many different values of x is \sqrt{\frac{48}{x}} a whole number?

Explanation:

The fraction expression is:

You need to find the divisors of 48 that make 48/x a perfect square:

The perfect squares less than 48 are 1, 4, 9, 16, 25, and 36.

The divisors of 48 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48.

Only 48/3 = 16, 48/12 = 4, and 48/48 = 1 are perfect squares.

Thus, 3, 12, and 48, are the values of x that make the expression a whole number.

Those are 3 numbers.

Hence, the answer is that there are 3 different values of x that make the fraction a whole number.

true

step-by-step explanation:

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
