Answer:

  • a. \bold{45000\times \:10^7}
  • b. \bold{3500}

Step-by-step explanation:

a. \left(5\times \:10^3\right)\left(9\times \:10^7\right)

5\times 10^3 = 5000\\\\5000\times \:9\times \:10^7

\mathrm{Multiply\:the\:numbers:}\:5000\times \:9=45000

=45000\times \:10^7

b. \left(7\times 10^5\right)\div \left(2\times 10^2\right)

\left(7\times 10^5\right)\div \left(2\times 10^2\right)=\frac{7\times \:10^5}{2\times \:10^2}

\frac{10^5}{10^2} = 10^3

\frac{7\times \:10^3}{2}

\mathrm{Factor}\:\: 10^3 : 2^3\times5^3

\frac{7\times \:2^3\times \:5^3}{2}

\frac{2^3}{2}=2^2

7\times \:2^2\times \:5^3=3500
