Expressed in figures, the number represented by 1.76 x 109 is equal to 1,760,000,000.
7000 is a number with ambiguous zeroes. Written this way, we can't be sure whether or not the zeroes are significant. You have specified 2 sig figs, so we must use scientific notation.Scientific notation specifies:A nonzero digit (1-9) in the 'ones' placeA decimal for two or more sig figsEvery significant digit must be shown, including all significant zeroesA factor of ten raised to a power to move the decimal to the correct placeIn this case, the seven and a zero are significant.7.0We need to move the decimal three places to have an equivalent answer7.0 * 103
Well, technically 3 to the power of the 2 is the exact same thing as 3 squared because if some number is to the power of 2, in mathematical terms it is squared.

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....

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.
7.360 x 10 to the power of -3 i think
Three, the power of ten is only to indicate the relative size.
9-5 = 1/95. Expressed as a decimal, rounded to three significant figures, this is equal to 0.0000169.
