Answer:

#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!

Answer:

#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 #
