Question

0.00003/2x10^-5 in scientific notation

Answer 1

`1.5 * 10^(1\\)`

Explanation:

First, let us turn the numerator into scientific form

We can see that after the decimal point, there are 4 zeros that come before the 3, so 0.00003 becomes

`0.00003 = 3 * 10^(-4)`
Now let's simplify the fraction

`(3\cdot 10^(-4))/(2 \cdot 10^(-5)) \\\text{Use exponent laws to get} \\(3\cdot 10^(-4 - (-5)))/(2) = (3\cdot10^1)/(2) = (30)/(2) = 15`

So our answer is 15 :3. We can write in scientific form as
`1.5 * 10^(1\\)`
