Question

somebody help please.. Compute and write your answer in scientific notation. (5.2 x 1013) (7.1 x 10-22)

Answer 1

@pooja can you help

Answer 2

I can

Answer 3

3.74 x 10^-18


am damn sure.

Answer 4

no direct answers @srinuscooby it's against the code of conduct

Answer 5

thanksbloomlocke367 its been dead on here for a while..

Answer 6

okay, just to be clear... it's\[(5.2\times 10^{13})(7.1\times 10^{-22})\] right?

Answer 7

yes that's correct

Answer 8

okay, hang on... what I'm doing isn't giving me the correct answer... so I'm trying to figure out what I'm doing wrong so I can help you

Answer 9

ok

Answer 10

okay... you first have to multiply the coefficients (5.2 and 7.1)

Answer 11

ok 36.92 is what I got

Answer 12

yup XD that's the first part.. then you multiply the other part (you'd have to add the exponents)

Answer 13

@Danny.Mcintire7

Answer 14

Problem solved ?
or should I send the full procedure @BloomLocke367

Answer 15

what do you mean?..

Answer 16

U were the one who said "No direct answers"
I thought you might have finished the answer hence :)

Answer 17

Oh.. I'm waiting for @Danny.Mcintire7 to respond to give him the final step

Answer 18

im confused on the last step you were talking about?

Answer 19

is it 10^33

Answer 20

I mean 10^35

Answer 21

okay... you have \(10^{13}\) and \(10^{-22}\) that you have to multiply... but to multiply exponents you have to add them

Answer 22

what's 13-22?

Answer 23

10^9

Answer 24

no... it's -9... because it's 13-22, not 22-13

Answer 25

oh ok my bad

Answer 26

okay... so far you have \(36.92 * 10^{-9}\)

Answer 27

ok

Answer 28

but that's not scientific notation yet.. because there should only be one digit on each side of the decimal.

Answer 29

do you know how to change it?

Answer 30

no im not sure

Answer 31

you just need to move the decimal over and change the exponent to correspond to it..

Answer 32

im confused I don't know how to do that or what it would look like?

Answer 33

and you can keep it like that...

Answer 34

do you understand now?

Answer 35

oh ok

Answer 36

do you understand now?

Answer 37

do I need to keep moving it over or not?

Answer 38

nope. as long as there is only ONE number to the left of the decimal.

Answer 39

ok awesome thanks you!:]
