For a multiplication or division, you should check how many significant figures each of the factors has, and take the least of them. This is the number of significant figures you should keep in the answer.
In general, the answer below is correct.
However, there is another approach to answering the question. The first number belongs to the interval (101.65, 101.75). The second is in (5.445, 5.455). Their product is, therefore, in the range (553.48425, 555.04625). Therefore, in terms of significant figure, the product is 550, to two sig fig.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
First write out the problem: 3.27*108= x * 6.43 * 1017 Divide both sides by 6.43 * 1017 (3.27/6.43) * 108-17=x .509 * 10-11=x (Notice that I rounded it to 3 significant figures) If you want to put it in scientific notation then the answer is 5.09 * 10-12
-1299
1299
7.32 X 1017 = 732,000,000,000,000,000 ====================Whatever that figures name is.
The factors of 1017 are: 1, 3, 9, 113, 339, 1017.
1017 = MXVII
-282 + (-1017) = -282 - 1017 = -1299
735
The positive integer factors of 1017 are: 1, 3, 9, 113, 339, 1017
1017 is less than 1318
-1073
yes ofcourse 1017/3=339
