Question

Use a single digit times a power of 10 to estimate the number 0.00004167.

Answer 1

Answer:

a. $0.00004167 = 0.00004$

b. $4* 10^{-5}$

Step-by-step 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:

$4* 10^{-5}$
