1.0 x 10^2
If you are rounding off to two significant figures the result is 33.Sixes always round up to the next higher digit i.e.296 to two significant figures is 30 *101
Assuming 5 is not an exact value, the 5 has one significant figure and the 5.364 has four significant figures. 5.364 x 5 = 26.82 However, since 5 only has one significant figure, you would round the 26.82 to be 30 or 3 x 101 30 has one significant figure.

62 rounded to one significant figure is 60. 57 rounded to one significant figure is 60. 573 rounded to one significant figure is 600. 0.0573 rounded to one significant figure is 0.06. In each of these answers the 6 is the only significant figure.
Three in 150.With trailing zeros it can be ambiguous.One thing is certain: if you use scientific notation there is nor doubt.In scientific notation one hundred fifty can be written as1.5 * 102 in which case there are two significant figuresor it can be written as1.50 * 102 (or 15.0*101) with three significant figures [However there also is one trailing zerohere!]or as1.500 * 102 (four significant figures) this also could be expressed as 150.0 - no doubt there that there are four significant figures for zeros to the right of the decimal point!
To round numbers to 3 significant figures, identify the first three non-zero digits from the left. If the digit after the third significant figure is 5 or more, round up the last significant figure. If the digit after the third significant figure is less than 5, keep the last significant figure the same. Trailing zeroes can be kept to maintain the significant figures.
5.7*101 or 5.7 E1
I believe you mean how many feet are in 101cm.1 foot = 30.48cm1cm = 0.032808399 feetTherefore: 101cm = 0.032808399*101 = 3.3136483 feet3.3 feet to 2 significant figures
If you were asked to round to the nearest 100, any number between 50 and 99 inclusive would round to 100. Also any number between 101 an 149 inclusive would round to 100.
70 in scientific notation is 7 x 101 (might show up as 7E1 on some calculators). Watch out for significant figures and avoid 7.0 x 101 as the zero is not a sig fig in this case since there is no decimal.
Four. All non zero numbers are always significant. Zeroes that are between non zero numbers are always significant. Zeroes that are to the right of a non zero number and that contain a decimal point are significant.
