Thank you for the opportunity to help you with your question!

4 times 10^12+(1.8 times 10^9)(2.6 times 10^3)

=4 times 10^12+(1.8 *2.6 * 10^9 *10^3)

=4 times 10^12+4.68 * 10^12

=(4+4.68) 10^ 12

= 8.68 * 10^12

5 times 10^14+(2.44 times 10^4)(1.4 times 10^10)

=5 times 10^14+(2.44 * 1.4 10^4 * 10^10)

=5 times 10^14+ 3.416 * 10^14

= (5+ 3.416) * 10^14

=8.416 * 10^14
