Question

how do you write 3.069 × 10^{-8} in standard form?

Explanation:

Step1: Recall scientific - to - standard conversion

For a number in scientific form $a\times10^{n}$, when $n<0$, move the decimal point $|n|$ places to the left.

Step2: Move the decimal point

For $3.069\times 10^{-8}$, since $n = - 8$, move the decimal point 8 places to the left. Add zeros as needed. So we get $0.00000003069$.

Answer:

$0.00000003069$
