You can put this solution on YOUR website! This is an exponential notation where for the sake of convenience , we write the small numbers as in the above problem first as numbers starting with units place devided by the required power of 10 so as to equal the given number .Then we substitute the notation yy E xx where yy represents the number with units place mentioned first and xx represents the power of 10 obtained above.IT IS IMPORTANT TO NOTE THAT WE HAVE TO USE -ve OR +ve SIGN BEFORE XX NUMBER APPROPRIATELY DEPENDING ON WHETHER WE HAVE TO DEVIDE OR MULTIPLY THE POWER OF TEN TO GET THE GIVEN NUMBER. It ineffect means that the given number is equal to that given on the left of symbol E (yy) multiplied by 10 to the power of the number given to the right of E (xx).The following small example will illustrate the procedure.
0.32=3.2/10 =3.2 E -1 since 3.2 is devided by 10 to the power of one to get the given number.
Similarly 32 =3.2*10 =3.2 E 1 since 3.2 is multiplied by 10 to the power of one to get the given number.
Hence the solution to the given problems are
0.0009255==9.255 E -4
0.000000005317==5.317 E -9
