The number 1.89 x 10^3 has three significant figures. The digits 1, 8, and 9 are all non-zero digits, which are always considered significant. The exponent (10^3) does not affect the count of significant figures; it merely indicates the scale of the number. Thus, the significant figures are solely determined by the digits in the coefficient, which is 1.89.
What you are asking is not clear, but I think that you're asking, "Why do you use x10 with scientific notation (Correct me if I'm wrong). The x10 is used because if you multiply something by ten, the decimal place of the number moves one to the right. If you divide a number by ten the decimal place moves one to the left. The x10(to whatever number) is just an easier way to symbolize that decimal place moving
The former is greater
One sequence could be -4, x10, -4, x10, ect.. So the sequence will be 10, 6, 60, 56, 560, 556, 5560, ect..

To convert to meters, x10-2 for centimeters and x10-1 for decimeters.
2 of them.

There are three significants in 750, only left zeroes (leading nills) are not significant.0.75 x10+3 has two, 0.750 x10+3 has three significants.* * * * *No, there are only 2 sig figs.
1.357 x10-3 in standard notation is: 0.001357
