The number 6,870,000,000,000,000 would appear in scientific notation on a calculator screen as b. 6.87E15
Scientific notation
Scientific notation is the way of expression a number in the form a × 10ⁿ Where a is number and where 1 ≤ a < 10 and n is the exponent and n is an integer.
- To write the number 6,870,000,000,000,000 in scientific notation, we count the number of decimal places to the right of the first digit which is 6. So, there are 14 decimal places after the first digit 6. The number of decimal places will be the value of n. So, n = 15.
- Now, we put a decimal point after the number 6 and remove all the zeros after 7 to get a. So, a = 6.87
We now have the value of a and n.
So, 6,870,000,000,000,000 in the form a × 10ⁿ is 6.87 × 10¹⁵
