Answer:
The result of the multiplication is [tex]28.52 \times 10^{-2}[/tex]
Step-by-step explanation:
In scientific notation, 40 can be represented as: [tex]4 \times 10^1[/tex]
Multiplication:
Multiply the coefficients and the powers. So
Coefficients: [tex]7.13 \times 4 = 28.52[/tex]
Powers: [tex]10^{-3} \times 10^1 = 10^{-3+1} = 10^{-2}[/tex]
Multiplication: [tex]28.52 \times 10^{-2}[/tex]
