(Note: In Problems, assume a number like 6.4 is accurate to ?0.1: and 950 is ? 10 unless 950 is said to be ?precisely? or ?very nearly? 950. in which case assume 950 ? 1.)

(I) Write out the following numbers in full with the correct number of zeros: (a) 8.69 X 104 (b) 9.1 X 103, (c) 8.8 X 10-1 (d) 4.76 X 102 and (e) 3.62 X 10-5.

Solution: 4P

The correct number of zeroes in the following numbers:

Remarks: To write a number in scientific notation, we write it as a product of a single digit and a power of 10.

8.69x104To write the following number is full multiply 8.69 with 10000

Hence 8.69 x 104 = 86900

(b) 9.1x103

To write the following number is full multiply 9.1 with 1000

Hence...
