7-4 Skills Practice Scientific Notation «AUTHENTIC ›»

Example: ( (3 \times 10^4) \times (2 \times 10^5) = 6 \times 10^9 ) Divide the coefficients, subtract the exponents: [ \fraca \times 10^mb \times 10^n = \fracab \times 10^m-n ]

Example: ( \frac6 \times 10^72 \times 10^3 = 3 \times 10^4 ) Exponents must match. Rewrite numbers with the same exponent, then add/subtract coefficients. 7-4 skills practice scientific notation
