SCIENTIFIC NOTATION The smallest distance between Earth and Mars is about 58 million kilometers. Decimal OR Notation 58,000,000 km Scientific Notation OR 5.8 x 107 km SCIENTIFIC NOTATION The thickness of a human hair is about 95 hundred-thousandths of a meter. OR 0.00095 m OR 9.5 x 10 – 4 m Decimal Notation Scientific Notation SCIENTIFIC NOTATION CONVERT THE FOLLOWING TO DECIMAL NOTATION: 4.56 x 104 = 45,600 3.015 x 10- 6 = (Move decimal 4 places right) 0.000003015 9.13 x 100 = 9.13 4.1 x 10- 2 = .041 (Move decimal 6 places left) (Do not move the decimal) (Move decimal 2 places left) WHEN CHANGING FROM S.N. TO DECIMAL FORM: IF THE POWER OF TEN IS POSITIVE, MOVE DECIMAL RIGHT. IF THE POWER OF TEN IS NEGATIVE, MOVE DECIMAL LEFT. SCIENTIFIC NOTATION CONVERT THE FOLLOWING TO SCIENTIFIC NOTATION: 333,000 = 3.33 x 105 0.000702 = 7.02 x 10- 4 3.14 = 3.14 x 100 0.58 = 5.8 x 10- 1 WHEN CHANGING TO SCIENTIFIC NOTATION: Move decimal to a position so that there is only one non-zero number to the left of the decimal point. SCIENTIFIC NOTATION CONVERT THE FOLLOWING TO SCIENTIFIC NOTATION: 333,000 = 3.33 x 105 0.000702 = 7.02 x 10- 4 3.14 = 3.14 x 100 0.58 = 5.8 x 10- 1 WHEN CHANGING TO SCIENTIFIC NOTATION: DECIMAL NUMBER > 10 … POWER OF TEN IS POSITIVE DECIMAL NUMBER < 1 … POWER OF TEN IS NEGATIVE DECIMAL NUMBER BETWEEN 1 & 10 … POWER OF TEN IS ZERO SCIENTIFIC NOTATION MULTIPLICATION IN SCIENTIFIC NOTATION: (3 x 104)(2 x 107) = (3•2) x (104•107) = 6 x 1011 (5 x 106)(7 x 1020) = 35 x 1026 ? = 3.5 x 1027 IF YOU MOVE THE DECIMAL TO THE LEFT, IT INCREASES THE POWER OF TEN BY THE NUMBER OF PLACES MOVED. ? 7.2 x 10- 6 (8 x 10- 12)(9 x 105) = 72 x 10-7 = POLYNOMIALS A POLYNOMIAL is a monomial or a sum (or differences) of monomials. A BINOMIAL is a polynomial with two terms. (or the sum of two monomials) A TRINOMIAL is a polynomial with three terms.
