Question

An atom is a small unit of matter. a small atom measures about 0.0000000001 meter. write the decimal as a power

Answer 1

It's simple. Count the number of digits after decimal and put the same number of zeroes after 1.

There are 10 zeroes after decimal.

So,
`0.0000000001 = (1)/(10000000000)`


`0.0000000001 = (1)/(10^(10))`


`0.0000000001 = 1 * 10^(-10)`
