Step 1

Since you have posted a question with multiple sub-parts, we will solve the first three subparts for you. To get the remaining sub-part solved please repost the complete question and mention the sub-parts to be solved.

Scientific notation for a given can be written as

x x 10^y

Here x is a number or decimal number such that

1 ≤ |x| < 10.

y is the power of 10 essential to make the scientific notation mathematically equal to the original number.
