If you meant 0043 then the scientific notation is 4.3 x 10^1. If you meant .0043 then the scientific notation is 4.3 x 10^-3.
That is the standard notation. If you meant 3.14 x 10^3 then the standard notation would be: 3,140
3 x 107 is already in scientific notation (: 30,000,000 is the standard notation (if that's what you meant to ask)
1 x 10^9 in standard notation is 1,000,000,000If you meant 110 to the ninth power (110^9) then the standard notation is 2,357,947,700,000,000,000
04.5 is in fractional notation - a decimal fraction. However, I assume you meant in the form of a ratio.The answer is 45/10 or 9/2
730.000 = 7.3*102 But if you meant 730,000 = 7.3*105
Not sure about scienctifc nontation but if you meant scientific notation, the answer is 4.8*10-1
106.23
It's already in base 10 ! If you meant scientific notation it's 1.25 x 105
18 is already a decimal number. If you meant 1/8, then this is written in decimal notation as 0.125.
The person might have meant 490 (literally 10 before 500), but standard notation for 490 would be CDXC
That depends by what you mean by "with an exponent". If you meant an exponent as in "to the power of" then 6 ** 2 = 6 * 6 = 36 If you meant the exponent in scientific notation then 6E2 = 6 * 10 ** 2 = 600
