Question

Find the sum, difference, product, and quotient of 6 x 10-4 and 1.5 x 10-4. Write your answers in scientific notation. The sum is The difference is The product is The quotient is

Answer 1

The sum is:

$6\times10^{-4}+1.5\times10^{-4}=7.5\times10^{-4}$

The difference is:

$6\times10^{-4}-1.5\times10^{-4}=4.5\times10^{-4}$

The product is:

$(6\times10^{-4})(1.5\times10^{-4})=9\times10^{-8}$

The quotient is:

$\frac{6\times10^{-4}}{1.5\times10^{-4}}=4$
