28n^7

Explanation:

Using PEMDAS (parentheses, exponents, multiplication/division, addition/subtraction) for the order in which you solve mathematical expressions, we can simplify this expression.

First, we simplify the exponent:
(2n^3)^2 = 4n^6

Now we multiply that by 7n:
7n * 4n^6 = 28n^7

Hope this helps!

28n^7

Explanation:

first simplify what is in the parentheses,
(2n^3)^2
square each term, 2^2 and (n^3)^2
remember when you put an exponent to another power you multiply them
so you end up with
4n^6
now all you have to do is multiply 7n (4n^6)
you get 28n^7
