Answer:

1. A 2.C 3. C

Explanation:

To find the total number of pencils produced over four years, you can multiply the annual production by the number of years:

Annual production = 1.8 x 10^6 pencils per year

Number of years = 4

Total production = Annual production x Number of years

Total production = (1.8 x 10^6 pencils/year) x 4 years

Now, calculate the total production:

Total production = 7.2 x 10^6 pencils

So, the total number of pencils produced over four years is 7.2 x 10^6 pencils.

To multiply the two numbers in scientific notation, you can multiply the significant figures and add the exponents of 10:

(8 x 10^(-2)) * (2.4 x 10^(-3)) = (8 * 2.4) x 10^((-2) + (-3))

Now, calculate the multiplication of the significant figures and the addition of the exponents:

(8 * 2.4) x 10^((-2) + (-3)) = 19.2 x 10^(-5)

So, the result is 19.2 x 10^(-5) in scientific notation.
