Answer:

a.
0.00004167 = 0.00004

b.
4* 10^(-5)

Explanation:

Given


0.00004167

Solving (a): Round to the nearest hundredth thousandth

This means there would be 5 digits after the decimal.

So:


0.00004167 = 0.00004 -- (approximated)

(b) Express in standard form

A number in standard form has the following format;


a * 10^b

Where


1 \leq a \leq 10

So:


0.00004167

becomes


4.167 * 10^(-5)

This is because the decimal point was moved 5 places backwards

Approximate 4.167 to nearest integer; We have:


4* 10^(-5)
