a student is attempting to simplify the exponent shown below. which statement best applies to the sample mathematical work?
given (2x/y)^9* (x/3)^2
step 1: i first apply the exponent in the left term, which gives the quantity 8x^3/y^3
step 2: i next apply the exponent in the right term, which gives the quantity x^2/9
step 3: i combine the two terms from step 1 and step 2 and simplify to get a final answer of 8x^6/9y^3

a.
the student incorrectly applies the exponent in step 1.
b.
the student incorrectly applies the exponent in step 2.
c.
the student incorrectly combines the results from steps 1 and 2 in step 3.
d.
the mathematical work shown is correct.
