Simplify the expression.
(3xy3)2(xy)6
3x8y12
9x8y9
2x3y12
9x8y12

Step-by-step explanation:

The expression is:

we use the following rule to simplify the expression:

that is, we multiply the exponent inside the parentheses by the exponent outside the parentheses (also using ):

and we simplify the exponents and substitute :

We have not finished simplifying yet, since we have that x and y are repeated we must use the following law of exponents:

We add the exponents that each variable has.

thus, the expression becomes:

and we simplify the exponents:

which is the fourth option

d is the answer

step-by-step explanation:

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.
