If y is a positive integer, for how many different values of y is <img src="https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B144%5Cy%7D"
Citrus2011 [14]

Answer:

2

Explanation:

I'll explain later, it has to do with prime factors, and perfect cubes.

The two values of y that work are 18, and 144.

³√(144/<u>18</u>) = ³√(8) = 2 [whole number]

³√(144/<u>144</u>) = ³√(1) = 1 [whole number]

-6+x=-3
add 6 to both sides
6-6+x=6-3
0+x=3
x=3
