Question

Micah is taking a test. Here is his answer to one of the problems.

3^4 × 3^3 = 9^7

Find and correct his error.

Answer 1

3^7

You dont multiply out the 3. Justt add the powers in this case

Answer 2

Hope it makes sense

Answer 3

u add all of it?

Answer 4

Im not sure how u got that im confused

Answer 5

No. So, As an example, 2^3 x 2^2.

So, if you simplify we have 8 x 4, correct?

Answer 6

So we get 32.
if we add the exponents and leave the 2, as is, we have then 2^5 ok?

Answer 7

Multiply it out, 2x2x2x2x2 = 32

Answer 8

so 2^3 x 2^2 = 2^5

Same goes with 3^4 x 3^3 which is 3^7

Answer 9

Make sense?

Answer 10

ohh yeah so how would i write it all out on my homework?

Answer 11

I would say the answer is reall 3^7 and the mistakes that were made is that the 3's were *'d instead of just being left a 3?

Answer 12

Micah was not supposed to multiply out the 3. He only needed to add the exponents.

The correct answer is 3^4 x 3^3 = 3^7
