Question

question write the number 3.7×10⁻⁶ in standard form.

Explanation:

Step1: Recall negative - exponent rule

A number in scientific notation $a\times10^{-n}$ (where $1\leqslant a<10$ and $n$ is a positive integer) can be written in standard form by moving the decimal point $n$ places to the left.
For $3.7\times 10^{-6}$, since the exponent of 10 is - 6, we move the decimal point 6 places to the left.

Step2: Move the decimal point

Starting with 3.7, moving the decimal point 6 places to the left gives 0.0000037.

Answer:

0.0000037
