Question

PLEASE HELP

Answer 1

Is the number a "big" number or a "little" number?

Answer 2

@Mertsj Little

Answer 3

"Little" numbers have negative exponents when written in scientific notation so that narrows our choices to B and D

Answer 4

So its B? cause theres 7 zeros.

Answer 5

Notice that
\[10^{-7} = 1 \times 10^{^{-7}}\]
and
\[10^{-6}= 1 \times 10^{-6}\]

Answer 6

Where is the decimal point in the number "1" ?

Answer 7

No 0

Answer 8

If the decimal point is not written, it is always at the end of the number so 1 is the same as 1.

Answer 9

So, if you have the number 1 you would have to move the decimal point to the left to end up with .0000001

Answer 10

How many places to the left would it have to be moved?

Answer 11

Oh so 10^-6
