Question

What is the expression written using each base only once? 5^-13 x 5^-5 x 2^2

Answer 1

what answer did u get

Answer 2

I didn't get an answer yet. Normally it would be 5^-8 if it was just the first two variables, but the extra 2^2 throws me off.

Answer 3

Can anyone help me with this question?

Answer 4

ok r u allowed to use the calculator

Answer 5

No. Even if I could I couldn't rewrite the expression into another one using a calculator.

Answer 6

2^2 means nothing...it's like x^3 and y^2

Answer 7

\[\Large x^3 \cdot y^2 \implies x^3y^2\]

Answer 8

btw -8 is wrong

Answer 9

\[\large 5^{-13} \times 5^{-5} \implies 5^{-13 + -5}\]

Answer 10

\[\large 5^{-13}\times 5^{-5} \times 2^2\]
\[\large 5^{-13-5}\times 2^2\]

Answer 11

So it would be 5^-17 and then multiply that with 2^2, which would the final value would be 10^-15 or what?

Answer 12

still not -17

Answer 13

what is 13 + 5?

Answer 14

Oh 18 my bad haha

Answer 15

also 5^(-17) can't be multiplied to 2^2 like that. you have to do them seperately.

Answer 16

so what's -13 - 5?

Answer 17

-18.
And to phuong, so I leave the 2^2 separately?

Answer 18

like i said before you cant combine x^2 and y^3

Answer 19

you just put them side-by-side

Answer 20

i.e \[4^2 \times 3^3 = 4^2 3^3\]

Answer 21

unless you have a calculator then you input those numbers

Answer 22

Ah I see. So (5^18)(2^2) would be the answer?

Answer 23

nope not 18

Answer 24

missing soemthing ;)

Answer 25

Ah I'm sorry I keep forgetting!
(5^-18)

Answer 26

better

Answer 27
