Question

w

Answer 1

\[9^{1/3}*81^{1/3} \]

Answer 2

I think it is 81 but the answer said it was 9, what am I doing wrong?

Answer 3

\[\Large 9^{1/3}*81^{1/3}\]

\[\Large 9^{1/3}*(9^2)^{1/3}\]

\[\Large 9^{1/3}*9^{2*1/3}\]

I'll let you finish up

Answer 4

Sorry, I am only in 7th grad.. 9^1/3 is 3.

Answer 5

But I am confused on the 9^2*1/3 part

Answer 6

9^1/3 does NOT mean 9 times 1/3

Answer 7

if we wanted to say " 9 times 1/3" we would write 9*1/3

Answer 8

How do we do 9^1/3 then?

Answer 9

\[\Large 9^{1/3}*9^{2*1/3}\]

\[\Large 9^{1/3}*9^{2/3}\]

now use the rule (a^b)*(a^c) = a^(b+c)

Answer 10

hmm, so (9^1/3*9^2*1/3)= 9^1/3(9^2/3+c)?

Answer 11

you add the exponents at this point

Answer 12

so 9^1 because 1/3+2/3=1?

Answer 13

yep, then 9^1 = 9

Answer 14

anything to the first power is that number itself
