x ^ - 1/4 = 4 ^ -1/2
mean:
1 / fourth root of x = 1 / square root of 4
1 / fourth root of x = 1 / 2
Taking reciprocial of both sides:
fourth root of x = 2
Rise both sides to the power of four
x = 2 ^ 4
x = 16
q^ 1/2 = x mean :
square root of q = x
Rise both sides to the power of two
q = x ^ 2
q = 16 ^ 2
q = 256
If q^1/2 = x, x^-1/4 = 4^-1/2, what is the value of q? Plz help me!

x^-1/4 = 4^-1/2, what is the value of q?^
raise both sides to the - 4th power
multiply - 1/4 times -4 = 1
multiply -1/2 times -4 = 2
x = 4^2 x = 16 Now you can find q.
