3 to the square root of 21x
Which value of x makes the expression equivalent to 12 to the square root of 21?
3sqrt%2821x%29 = 12sqrt%2821%29
square both sides
9(21x) = 144(21)
189x = 3024
x = 3024/189
x = 16

See if that checks out
3sqrt%2821%2A16%29 = 12sqrt%2821%29
3sqrt%28336%29 = 12sqrt%2821%29
9(336) = 144(21)
3024 = 3024
