When rounding 7000 to two significant figures, you would look at the first two non-zero digits from the left. In this case, the first two non-zero digits are 7 and 0. Since the digit following 0 is greater than 5, you would round up the 0 to 1. Therefore, 7000 rounded to two significant figures would be 7100.
Expressed in figures, the number represented by 1.76 x 109 is equal to 1,760,000,000.
When expressing a number to one significant figure, you round the number to the nearest power of 10. In this case, 9862 to one significant figure would be 10,000. This is because the first digit from the left is 9, which is closer to 10 than 10000.

1) How did you come across such a big number?2) In 10 significant figures, the scientific form of the answer = 2.663730488x1090
it would be 0.03 just round up, two significant figures means two figures after the decimal point. If it was 3 significant figures then it would be 0.04 etc....

0.007359525 in scientific notation to 4 significant figures is 7.359 x 10^-3.
Three significant figures of 1.702 x 10^5 are 1.70 x 10^5.
significant figures are digits of certainty. In other words they are exact numbers. Except zeros are placeholders (not exact) unless if they are in between non zeros. Also zeros at the end of numbers are significant figures if there is a decimal point.
1 X 10 to the power of 0 The way that you would write the answer depends on the number of significant figures in your equation and the preference of your professor. 1x10^0 = 1 1.0x10^0 = 1 1e10^0 = 1 1.0e10^0 = Depending on the number of significant figures, you would simply add trailing zeros to the 1. Don't forget to put a period at the end if there is a long string of zeros as this denotes they are significant.
Three, the power of ten is only to indicate the relative size.
The number 502200 in scientific notation is written as 5.02200 × 10^5. This format expresses the number as a product of a coefficient (5.02200) and a power of ten (10 raised to the fifth power). In standard scientific notation, the coefficient is typically rounded to three significant figures, resulting in 5.02 × 10^5.
9-5 = 1/95. Expressed as a decimal, rounded to three significant figures, this is equal to 0.0000169.
