It depends on how many significant digits you require; assuming 3 it's 1.82x10^41.82 x 104
1 x 104 = 104 2 x 52 = 104 4 x 26 = 104 8 x 13 = 104

How many acres is 150 x 418 x 301 x 528?
Two of them.
There are 5 significant digits in 78000. Which is the same as 7.8 x 104.
4.15 x 104

-- If you're allowed to repeat digits in one combination,then there are 104 = 10,000 possibilities.-- If all four of the digits must be different, then there are(10 x 9 x 8 x 7) = 5,040 possibilities.
0000-9999 (10x10x10x10 or 104) = 10,000 possible combinations allowing for repeated digits. If you are not able to repeat digits then it's 10 x 9 x 8 x 7 or 5,040 possible combinations without repeated digits.
You would formulate this problem X/100 * 150 = 72 and solve for X.
For 104 they are: 104 = 1 x 104 104 = 2 x 52 104 = 4 x 26 104 = 8 x 13
104 x 2.54 = 264.16 inches
1 x 104 = 104 2 x 52 = 104 4 x 26 = 104 8 x 13 = 104
there are 4 cups in one quart so that means that 104 / 4 = x where 104 is the cups and x is the quarts. 104 / 4 = 26, so 26 quarts in 104 cups.
104 x 146 sq meter = (104 x 146)/ (0.3048 x 0.3048) sq feet
