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 Count the number of digits between the old and the new decimal point, this gives the power, n of 10 (10 n ) X 10 3 Since the decimal is shifted to the left, the exponent is positive x Digits

Question 6 Write 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 (10 n ). X Since the decimal is shifted to the right, the exponent is negative x Digits

Question 14 Write x 10 4 in standard form Write the decimal number Move the decimal the number of places specified by the powers of ten: to the right since it is positive. X Rewrite the number in integer/standard form. 49,530 4 Places

Question 17 Write x in standard form Write the decimal number Move the decimal the number of places specified by the powers of ten: to the left since it is negative. X Rewrite the number in integer/standard form Place

Multiplying and Dividing With Your Calculator 1.Punch the number (the digit number) into your calculator. 2.Push the EE or EXP button. Do NOT use the x (times) button!! 3.Enter the exponent number. Use the +/- button to change its sign. 4.Voila! Treat this number normally in all subsequent calculations. Scientific Calculator Scientific calculator for chemists with notebook
