Complete the question. Show your work and answer on the page. Find the quotient. Write your answer in scientific notation. (1.2×10^-5)÷4=

Answer 1

We are given the following division problem.

$1.2\times10^{-5}\div4$

Which can be re-written as

$\begin{gathered} 1.2\times10^{-5}\div4 \\ 12\times10^{-6}\div4 \end{gathered}$

We basically moved the decimal point to the right one time so -1 added to the power.

Now it is easier to perform the division

We know that 12 divided by 4 is equal to 3

So, the quotient is

$12\times10^{-6}\div4=3\times10^{-6}$

Therefore, the quotient in the scientific notation is

$3\times10^{-6}$
