Answer 5

whats ur problem, ur supposed to explain not just give the answers

Answer 6

@jim_thompson5910 @jabez177

Answer 7

@rainbow_rocks03 first you would multiply the base numbers 5.1 and 3.2

what do you get when you do this?

Answer 8

you get 16.32

Answer 9

yes

Answer 10

then you add the exponents 3+3 = 6

Answer 11

so \[\Large \left(5.1 \times 10^{3}\right)\times\left(3.2 \times 10^{3}\right) = 16.32 \times 10^{6}\]
but this is not the final answer. There's a bit more work needed to be done

Answer 12

Recall that scientific notation must have the base be a number x such that \(\Large 1 \le x < 10\)

Answer 13

5?

Answer 14

im not sure

Answer 15

is 16.32 between 1 and 10? the answer is no

so we must convert 16.32 into scientific notation

Answer 16

how can we do this?

Answer 17

idk

Answer 18

we can move the decimal point 1 spot to the left to go from 16.32 to 1.632

to move the decimal point back, we move the decimal 1 spot to the right

the `move the decimal 1 spot to the right` is the same as multiplying by 10 = 10^1

which is why

\[\Large 16.32 = 1.632 \times 10^{1}\]

do you agree?

Answer 19

um, yes

Answer 20

So replace the `16.32` with `1.632 x 10^1` to go from this
\[\Large 16.32 \times 10^{6}\]
to this
\[\Large 1.632 \times 10^{1} \times 10^{6}\]
with me so far?
