Given: %285.6+%2A+10%5E3%29+%2A+%28+4+%2A+10%5E5%29
5.6+%2A+4+%2A+10%5E3+%2A+10%5E5
+22.4+%2A+10%5E8 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+%2A+10%5E9
