Answer 2

0.0000000135 in scientific form is
`1.35 * 10^(-8)`

Step-by-step explanation:

According to question,

0.0000000135 is to be converted to scientific form to two significant figures

0.0000000135 can also be written as
`(135)/(10000000000)`

135 in decimal form can be written as
`(1.35 * 100) \text { or }\left(1.35 * 10^(2)\right)`

And 10000000000 =
`10^1^0`

Therefore,

`(135)/(10000000000)=(1.35 * 10^(2))/(10^(10))`

`(1.35 * 10^(2))/(10^(10))=1.35 * 10^(2-10)=1.35 * 10^(-8)`

Thus, 0.0000000135 in scientific form is
`1.35 * 10^(-8)`
