Work Step by Step

We start with the given expression: $(6\times10^5)(1.2\times10^{8})$ We use the associative property of multiplication to regroup the factors in a different way: $(6\times1.2)(10^5\times10^{8})$ We multiply the constants: $7.2(10^5\times10^{8})$ To multiply powers with the same base, we add the exponents: $7.2(10^{5+8})=7.2\times10^{13}$
