Answer 2

Option B: 0.000699 is the standard form

Step-by-step explanation:

Given that the expression
`6.99* 10^{-4`

We need to determine the standard form of the expression
`6.99* 10^{-4`

Since, the power is in negative four, then we need to move the decimal point four places before the number 6.

Moving the decimal point four places before the number 6, we get,

0.000699

Thus, the standard form of the given expression is
`6.99* 10^{-4`

Therefore, Option B is the correct answer.
