Question

Simplify and write answer in exponential form:

3^3 + 2 • 3^3

Answer 1

\[3\times3\times3+2\times3\times3\times3\]

Answer 2

My professor's answer was 3 x 3^3 but idk how she got that

Answer 3

Factor this: A + 2A

Answer 4

3A

Answer 5

Now try \((3^{3} + 2\cdot 3^{3})\)

Hint: It is EXACTLY the same.

Answer 6

I'm sorry, but I still don't understand this.. :(

Answer 7

one apple and two apples are three apples
one \(3^3\) and two \(3^3\) are three \(3^3\) and \(3\times 3^3=3^{1+3}=3^4\)

Answer 8

if your professor really wrote
\[3\times 3^3\] he/she was not paying attention

Answer 9

Try to see it this way: you have: 3^3 + 2 • 3^3,
so this is 1 • 3^3 + 2 • 3^3 = 3 • 3^3 (you have 3 times 3^3).

Last step: 3 • 3^3 = 3 • 3•3•3 = 3^4

(=81, I fail to see why you would stop after writing it as 3^4, just calculate the outcome...)

Answer 10

Omg! Thank you! That helped :)

Answer 11

YW!
