  3. Question 1 Write 4,776 in scientific notation Place the decimal immediately to the right of the left-most non-zero number. This should give you a number between one and ten. 4.776 Count the number of digits between the old and the new decimal point, this gives the power, n of 10 (10n). 4 776 3 Digits X 103 Since the decimal is shifted to the left, the exponent is positive. 4.776 x 103

  4. Question 6 Write 0.0246 in scientific notation Place the decimal immediately to the right of the left-most non-zero number. This should give you a number between one and ten 2.46 Count the number of digits between the old and the new decimal point, this gives the power, n of 10 (10n). 0 02 46 2 Digits X 10-2 Since the decimal is shifted to the right, the exponent is negative. 2.46 x 10-2

  5. Question 14 Write 4.953 x 104 in standard form Write the decimal number. 4.953 Move the decimal the number of places specified by the powers of ten: to the right since it is positive. 4 9530 X 104 4 Places Rewrite the number in integer/standard form. 49,530

  6. Question 17 Write 8.397 x 10-1 in standard form Write the decimal number. 8.397 Move the decimal the number of places specified by the powers of ten: to the left since it is negative. 0 8 397 X 10-1 1 Place Rewrite the number in integer/standard form. 0.8397

  7. Multiplying and Dividing With Your Calculator • Punch the number (the digit number) into your calculator. • Push the EE or EXP button. Do NOT use the x (times) button!! • Enter the exponent number. Use the +/- button to change its sign. • Voila! Treat this number normally in all subsequent calculations. • Scientific Calculator • Scientific calculator for chemists with notebook • http://www.calculator.com/calcs/calc_sci.html
