CALCULATOR SKILLS These problems are designed to give you practice using your calculator in operations with scientific notation. Report your answers in proper scientific notation. (Do not be concerned about significant figures now. You can go back and to this later after we’ve covered it in Chapter 2.) 1. Multiply: a) (6.1 x 10 13 ) × (4.532 x 10 7 ) = b) (9.876 x 10 ! 9 ) × (1.13874 x 10 ! 8 ) = c) (8.71 x 10 ! 15 ) × (4.65 x 10 8 ) = d) ( ! 5.39 x 10 8 ) × (2.157823 x 10 ! 5 ) = e) (0.00013805) × (3.77461 x 10 12 ) = 2. Divide: a) (1.987052 x 10 3 ) ÷ (3.678991 x 10 6 ) = b) (3.753 x 10 ! 7 ) ÷ (2.39 x 10 ! 14 ) = c) (8.94523 x 10 5 ) ÷ (6.2439 x 10 ! 9 ) = d) (5.679 x 10 ! 12 ) ÷ (2.997104 x 10 5 ) = e) ( ! 6.029 x 10 ! 6 ) ÷ (1.03 x 10 ! 7 ) = 3. Add: a) (1.23 x 10 4 ) % (9.876 x 10 3 ) = b) (1.23 x 10 2 ) % (9.876 x 10 ! 1 ) = c) (4.9921 x 10 ! 2 ) % (7.06182 x 10 2 ) = d) (1.03724 x 10 ! 9 ) % (9.913 x 10 ! 11 ) = e) (1.97236 x 10 ! 23 ) % (8.7110 x 10 ! 23 ) = OVER . . .
