Question

(a^5b^3) (a^4b^5)

Do I multiply for add the exponents? E.g. would I have a^9 or a^20? Thank you!

Answer 1

You add the exponents in this case

Answer 2

Oh my goodness... THANK YOU!!!!! Last time I had to ask this question, I was forced to wait 10 minutes for a wrong answer.

Answer 3

you're welcome

Answer 4

So it is a^9andb^8 correct?

Answer 5

bingo

Answer 6

THANK YOU! Can you answer one more quick question, please?

Answer 7

so \[\Large a^9b^8\]

Answer 8

(-2hi^3)(2h^2ij^3)

Answer 9

multiply -2 and 2 to get?

Answer 10

Would it be -4h^3i^4j^7?

Answer 11

The term for j is j^3 since the first expression doesn't have any j terms

Answer 12

or because

(-2hi^3)(2h^2ij^3)

really is

(-2hi^3j^0)(2h^2ij^3)

Answer 13

So i'm not sure how you're getting 4+3 = 7

Answer 14

-4h^2i^3j^12?

Answer 15

no

Answer 16

What are the exponents for j in

(-2hi^3j^0)(2h^2ij^3)

???

Answer 17

Do I not multiply -2 and 2?

Answer 18

yes those are the coefficients

Answer 19

0 and 3

Answer 20

add them

Answer 21

to get the final exponent for j

Answer 22

3

Answer 23

So the answer is \[\Large -4h^3i^4j^3\]

Answer 24

Thank you!!

Answer 25

Answer 26

Okay now, another one! :D

([3^2]^3g^5h^8)^2

Answer 27

What is [3^2]^3

Answer 28

Do you mind if I do the problem by myself, and I'll give you my answer and see if I'm right?

Answer 29

alright

Answer 30

Stay with me, please! :)

Answer 31

ok

Answer 32

729g^10h^16

Answer 33

Yes?

Answer 34

no it's not correct

Answer 35

Huh..

Answer 36

3^2 is 9

So [3^2]^3 = 9^3 = 729


This means

([3^2]^3g^5h^8)^2

becomes

(729g^5h^8)^2

Answer 37

did you get that as one of your steps?

Answer 38

Uhm

Answer 39

yes

Answer 40

Then you square everything inside

Answer 41

Oh!

Answer 42

tell me what you get

Answer 43

531,411g^10h^13

Answer 44

16

Answer 45

yes, but I would get rid of the comma....computer answer systems don't like commas

Answer 46

oh yes, 16 not 13

Answer 47

use only commas to separate out answers (like ordered pairs), don't enter commas for large numbers

Answer 48

kk

Answer 49

so the answer is

531411g^10h^16

which looks like

\[\Large 531411g^{10}h^{16}\]

Answer 50

uhm

Answer 51

what's wrong?

Answer 52

x(x^4)(x^6)

Answer 53

x = x^1

Answer 54

x^11?

Answer 55

So

x(x^4)(x^6)

is the same as

x^1(x^4)(x^6)

or

x^1 times x^4 times x^6

Answer 56

yes

Answer 57

x(x^4)(x^6) = x^11

Answer 58

Okay, one more question! :)

Answer 59

ok
