Question

express the following number in decimal notation: 4.22 x 10^(-3)
question 5
the prefix micro means: 10^6 10^(-3) 10^3 10^(-1) 10^(-6)

Explanation:

Question 4

Step1: Recall exponent - negative rule

For \(a\times10^{-n}\), we move the decimal point \(n\) places to the left. Here \(a = 4.22\) and \(n=3\).

Step2: Move the decimal point

Starting with 4.22, moving the decimal point 3 places to the left gives 0.00422.

The prefix "micro -" in the metric system represents \(10^{- 6}\). It is a standard unit - prefix used to denote a very small quantity.

Answer:

0.00422
