Standard form is the form you want. 100 = 1, 101 = 10, 102 = 100, 103 = 1000 etc Therefore if you want to write 300000000 in standard form it is 3 x 108 The same thing applies to decimals - 10-1 = 0.1, 10-2 = 0.01, 10-3 = 0.001 etc Therefore if you want to write 0.0000004 in standard form it is 4 x 10-7 Note, that the number you multiply the power of ten to must be between 0 and 10 for example - 45600000 CANNOT be written as 456 x 105 but MUST be written as 4.56 x 107 also 0.00000345 CANNOT be written as 345 x 10-9 but MUST be written as 3.45 x 10-7.
