Question 141030
Given: {{{(5.6 * 10^3) * ( 4 * 10^5)}}}
{{{5.6 * 4 * 10^3 * 10^5}}}
{{{ 22.4 * 10^8}}}  since in scientific notation, the constant must always fall between 1 and 10, we need to shift the decimal one place to the left. In order to keep the number value equivalent, we must then add one to exponent as well.

{{{ 2.24 * 10^9}}}
