standard form for scientific notatnio is
(number more than or equal to 1 and less than 10) times 10^x
maybe you want to multiply it out so
10^3=10 times 10 times 10=1000
basically, if positive, move the decimal place to the right the exponent number of spaces
if negative do move to the left
first one
4 times 10^9
4 with 9 zeroes after it
4,000,000,000
this is in standard form
2nd one
2 times 10^-5
move decimal place 5 places to the left
0.00002
3rd
3.7 times 10^6
6 places to the right
3,700,000
4th
3 times 10^8
8 zeroes
300,000,000
