Determine the values of a and k when 299,790,000 is written in scientific notation.

The value of a=2.9979 and the value of k is 8.

Further details:

As the normalized form of scientific notation is

                     a×10^k

so when we write the value of 299,790,000 into scientific notation, it would be written as

                    2.99×10^8

So, by viewing this equation, the value of a=2.9979 and the value of k is 8.

Scientific notation:

Scientific notation (also stated to as scientific form or standard index form, or standard form in the UK) is a way of conveying numbers that are too big or too small to be appropriately written in decimal form. It is usually used by scientists, mathematicians and engineers, in part as it can simplify definite arithmetic processes.  

Significant numbers:

A significant figure is a digit in a number that enhances to its precision. This comprises all nonzero numbers, zeroes between significant digits, and zeroes specified to be significant. Leading and behind zeroes are not significant because they present only to show the scale of the number.
