Question

how do you simplify 3^4+2X3^4

Answer 1

That X is a times sign?

Answer 2

yes

Answer 3

All right, just making sure. Later on you'll stop using x for times.

Answer 4

yes i know, but there is no dot sign on a keyboard

Answer 5

Well, we have to use order of operations here.

Answer 6

Ah, normally you just use an asterisk. *

Answer 7

well whatever

Answer 8

3^4+2X3^4
We do the exponents first.
3*3*3*3+2*3*3*3*3
9*9+2*9*9
81+2*81
3*81
243

Answer 9

yes. i get that. how do you convert that to exponential form then?

Answer 10

We started out in exponential form.

Answer 11

yes. the answer i need has to be in exponential form
it is a test question

Answer 12

We started out in exponential form.

Answer 13

ok. so how do you get back to it?? in a simplified version????!!

Answer 14

Well, you wouldn't just start out with a number like 243.
They would give you something like
3*3*3*3+2*3*3*3*3
and you would answer
3^4 + 2 * 3^4

Answer 15

the simplified answer is 3^5

Answer 16

Of course, if they gave you 81 you could say 9^2

Answer 17

but that is not the same.. that original problem is equal to 243
so the simplified version which is 3^5 must equal 243

Answer 18

Well, to be truthful I'm not sure how you ended up with 3^5. It works, but I don't know why. Perhaps you could ask someone else? I though by simplify you meant find the simplest form, which is 243.

Answer 19

nope
thanks
