Question

(2a)exponent 3

Answer 1

\[8a^3\]

Answer 2

\[(2a)^3=2^3a^3=8a^3\]

Answer 3

what did you do to get 8?

Answer 4

2^3 means 2*2*2=8

Answer 5

8A^2

Answer 6

oh, duh! i knew that.

Answer 7

:)

Answer 8

will you help me with just one more question?

Answer 9

sure thing

Answer 10

(x^2 y^2)^4xy^5

Answer 11

Is that \[(x^2y^2)^4xy^5\]

Answer 12

yes

Answer 13

\[x^{2*4+1}y^{2*4+5}\]
\[=x^9y^13\]

Answer 14

^^^^AGREE

Answer 15

That's supposed to be 9 and 13 by the way, it's a bit messy sorry.

Answer 16

If so then the 4 is applied to both factors inside the parentheses first\[(x^2)^4(y^2)^4xy^5\]then you have\[x^8y^8xy^5= x ^{9}y ^{13}\]

Answer 17

okay, so my answer would be x^9 y^13?

Answer 18

Exactly

Answer 19

thankyou so much!!!!

Answer 20

i tried this one on my own and i was just wondering if you could tell me if i did it right..... the question is: 12x^8/3x^6 and i got 15x^14

Answer 21

NO MEDALS FOR ME :(

Answer 22

thats confusing

Answer 23

If the 3x^6 is in the denominator, then you have an error, x^8/x^6=x^2 it should be in the numerator. 12/3 would reduce to 4 so the answer would be 4x^2.

Answer 24

There was no 15, I accidentally pulled it from your answer.

Answer 25

The meaning of x^8 is that there are 8 factors of x in the numerator; the meaning of x^6 is that there are 6 factors of x in the denominator. The 6 factors of x in the deniminator cancel 6 of the 8 factors of x in the numerator leaving 2 factors of x in the numerator.
