Numbers written in scientific forms are said to be in standard forms

The values of a and b are a and -3, respectively.

How to determine the values of a and b

The equation is given as:

[tex]4.5 * 10^{-3} - 3.4 * 10^{-5} = a * 10^b[/tex]

Rewrite the expression as:

[tex]4.5 * 10^2 * 10^{-5} - 3.4 * 10^{-5} = a * 10^b[/tex]

Multiply 4.5 and 10^2

[tex]450 * 10^{-5} - 3.4 * 10^{-5} = a * 10^b[/tex]

Factor out 10^-5

[tex](450 - 3.4 ) 10^{-5} = a * 10^b[/tex]

Evaluate the difference

[tex]446.6 * 10^{-5} = a * 10^b[/tex]

Rewrite as:

[tex]4.466 * 10^2 * 10^{-5} = a * 10^b[/tex]

[tex]4.466 *10^{-3} = a * 10^b[/tex]

By comparison, we have:

a = 4.466

b = -3
