In a Library stack there are 4 books each of thickness 24 mm and 6 paper sheets each of thickness 0.015 mm. What is the total thickness of the library stack in scientific notation?
4*24 + 6*0.015

To find the total thickness of the library stack, we need to calculate the sum of the thicknesses of the books and the paper sheets.
First, let's calculate the thickness of the books:
Each book has a thickness of 24 mm. Since there are 4 books, the total thickness of the books is 4 * 24 mm.
Next, let's calculate the thickness of the paper sheets:
Each paper sheet has a thickness of 0.015 mm. Since there are 6 paper sheets, the total thickness of the paper sheets is 6 * 0.015 mm.
Now, we can calculate the total thickness of the library stack by adding the thicknesses of the books and the paper sheets:
Total thickness = thickness of the books + thickness of the paper sheets
Total thickness = (4 * 24 mm) + (6 * 0.015 mm)
Total thickness = 96 mm + 0.09 mm
Total thickness = 96.09 mm
In scientific notation, 96.09 mm can be written as 9.609 x 10^1 mm.
