7^(7n + 7) = 2401
apply log on both sides to solve the equation
log 7^(7n + 7) = log 2401
the power is brought forward
(7n + 7) log 7 = log 2401
7n +7 = log 2401 / log 7
7n + 7 = 4
7n = -3
n = -3/7

C. -X to the 3rd power, 4x to the second power and 5x all share the common factor or X, therefore you put it outside the parenthesis. What you have left is -X to the second power minus 4x minus 5.
(x-1)(x-9)
Hope this helps
Hello!
Let's subtract the eight DVDs Joe received as gifts, because he didn't buy them on his own.
35 - 8 = 27
Now, divide the remaining CDs by the 3 years he collected his DVDs in.

Joe bought 9 DVDs last year.
Good day!
