Question

yep! now simplify the expression then click check. leave any boxes blank if they should not have an exponent.
power rule for exponents
$(x^a y^b)^c = x^{ac}y^{bc}$
$(2y^{1/4})^4 = 2^{(1)4}y^{(1/4)4}$
$= 2^4 y^1$
$= \square y^{\square}$

Explanation:

Step1: Calculate $2^4$

$2^4 = 2\times2\times2\times2 = 16$

Step2: Simplify $y^1$

$y^1 = y$ (exponent 1 can be omitted)

Answer:

$16y$ (the first box is 16, the exponent box for $y$ is left blank)
