Question

i need help fan and medal

Answer 1

how do you get 9.49*10^3 kg from 2.48*10^2 kg + 9.17*10^3 kg+7.2*10^1 kg

Answer 2

@hershey21 You should firstly make all the powers same & then take them as common & then add...........

Answer 3

\[2.48kg * 10^{2} = 2\]
\[9.17kg * 10^{3} = 9170kg\]
\[7.2 * 10^{1} = 72kg\]

Answer 4

\[248 kg * \] oops sorry for this error

Answer 5

\[248 + 9170 + 72 = 9490kg \]

Answer 6

\[9490kg = 9.49kg * 10^{3}\]

Answer 7

nevermind about what I said I mean why did you add a zero to the and of 917

Answer 8

no no i think i mentioned again there was a typing error , u don't round off
2.48 * 10^2 = 248kg
Look at the added value, i have added 248 ! not 2 :)

Answer 9

nevermind about what I said I mean why did you add a zero to the and of 917

Answer 10

10^3 = 1000 right?

Answer 11

yes

Answer 12

so 9.17kg * 1000 = 9170kg

Answer 13

ohh ok

Answer 14

thanks

Answer 15

Ok

Answer 16

@Rushwr I have another question for this equation I'm kind of confused because of the negative but 4.07*10^-5mg +3.966*10^-4mg+ 7.1*10^-2 is the answer 4.4737*10^-5

Answer 17

\[10^{-5} = 0.00001 \] right?

Answer 18

um how is it 0.00001 im confused

Answer 19

\[10^{-5} = \frac{ 1 }{ 10^{5} } \] right?

Answer 20

yes

Answer 21

now divide 1 by 10^5 and see what's the value u get

Answer 22

Simply write 1 & place 4 zeroes before it so that 5 digits are after decimal point(.)

Answer 23

wow that was much easier @RamiroCruzo

Answer 24

so would you write one even if its 10^-6 or 10^-3

Answer 25

Use it whenever confused, you just need to place that much digits as there are in exponent power........
10^(6)= 0.000001

Answer 26

@hershey21 Is it okay now mate........

Answer 27

i think so am just redoing the equation again

Answer 28

so is it 7.14373*10^-2

Answer 29

Yup.......Congrats............

Answer 30

idk why @Rushwr but thank you @RamiroCruzo and @Rushwr have a nice day :)
