Question

Simplify. (3m)^-4

Answer 1

\[(3m)^{-4}\]

Answer 2

81m^-4

Answer 3

The problem says to use positive exponents only.

Answer 4

= 1/ (3m)^4

Answer 5

I can try.

Answer 6

Sorry, it's taking me a while i'm lost.

Answer 7

Where do you lost?

Answer 8

I dont know where to begin.

Answer 9

@Chlorophyll is it \[\frac{ 3 }{ m^4 }\]

Answer 10

= 1/ (3m)^4
So do you understand until here?

Answer 11

yeah

Answer 12

Since BOTH " 3" and "m" are INSIDE the bracket of power 4, you need to power ...?

Answer 13

i dont get it... power of 10?

Answer 14

( 3 m) ^4 = 3^4 * m^4 = ...

Answer 15

3m^16?

Answer 16

3^4 = 3 * 3 * 3 *3 = ...?

Answer 17

81

Answer 18

That how you power!

Answer 19

-> ( 3 m ) ^4 = ....?

Answer 20

I'm just really confused. I'll guess I have a time limit and I need to get this done but thank you for your help anyway :)

Answer 21

( 3 m) ^4 = 3^4 * m^4
= 3 * 3 * 3 *3 m^4
= ....?

Answer 22

81m^4? That doesn't look right but that is all I can think of, none of it makes sense to me.

Answer 23

NO, I mean you're correct but at the end the result is
= 1/ 81m^4

Answer 24

= 1/ (3m)^4
= 1/ 81m^4

Answer 25

It doesn't make because you don't learn the rule of power!

Answer 26

3^2 = 3*3 = 9
2^3 = 2 *2 * 2 = 8
3^4 = 3 * 3* 3* 3 = 81

Answer 27

I guess because you don't know how to use the calculator!

Answer 28

I don't use a calculator.

Answer 29

So you should use to check your manual work, also to understand it more!
