Question

can someone please help quick
Choose the correct simplification of the expression (3x)4
can you explain how you got your answer

Answer 1

(3x)*4
3x*4
3*4x
3*4
=12x

Answer 2

I assume that you mean
\[(3x)^{4}\]

is that correct?

Answer 3

You can see (for example) that
\[(2x)^{2} = (2x) * (2x) = 2*2*x*x = 2^{2}*x ^{2}\]

So you can put the power 4 into each factor inside the bracket...

Answer 4

the answer is 81x^4

Answer 5

how did they get that answer

Answer 7

I have given you the answer above.

more generally
\[(ab)^{n} = a ^{n}b ^{n}\]

in you case
a = 3
b= x
n= 4

so use my general case - put in your numbers and your answer will be there...

Answer 8

Use ^ to represent powers if oyu do not know the equation editor...
