1.5*104 = 104(3)(.5) = 312/2 = 156. 3 digits.
Two of them.
It depends on how many significant digits you require; assuming 3 it's 1.82x10^41.82 x 104
The number 8.500 x 10^4 has four significant digits. The digits 8, 5, and the two zeros after the 5 are all considered significant because they indicate precision in the measurement. In scientific notation, all digits in the coefficient (the number before the exponent) are counted as significant.
1 x 104 = 104 2 x 52 = 104 4 x 26 = 104 8 x 13 = 104

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.
The number 8.500 x 10^4 has four significant digits. The digits 8, 5, and the two zeros after the 5 are all considered significant because they indicate precision in the measurement. In scientific notation, all digits in the coefficient (the number before the exponent) are counted as significant.
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
To write 150 million in standard notation, you would use the numerical digits for the number and place commas to separate the digits into groups of three starting from the right. Therefore, 150 million would be written as 150,000,000 in standard notation.
