well this is simple

anonymous · Answer

first find the numeric value of 5.5 x10^5

anonymous · Answer

@ZachKetchup what would that be?

anonymous · Answer

just move the decimal 5 times to the right

anonymous · Answer

in 5.5

anonymous · Answer

how do you find the numeric value ?

anonymous · Answer

like I said, move the exponent number above the 10 to the right

anonymous · Answer

that would be 55 one, 550 two, 5500 three, 55000 four, and 550000 five

anonymous · Answer

@ZachKetchup  so now using a calculator, what is 550000 * 23000?

anonymous · Answer

remember, the number in scientific notaion cannot be more than ten or less than 1

anonymous · Answer

12 650 000 000
