![]() Interpret scientific notation that has been generated by technology. Students can complete patterns of base 10 exponents in different. Use scientific notation and choose units of appropriate size for measurements of very large or very small quantities (e.g., use millimeters per year for seafloor spreading). This interactive mathematics resource explores the meaning of positive and negative exponents. Perform operations with numbers expressed in scientific notation, including problems where both decimal and scientific notation are used. For example, estimate the population of the United States as 3 x 10^8 and the population of the world as 7 x 10^9, and determine that the world population is more than 20 times larger. The small number written above and to the right of a number is called an exponent. ![]() Use numbers expressed in the form of a single digit times an integer power of 10 to estimate very large or very small quantities, and to express how many times as much one is than the other. For example, writing 4 x 4 x 4 x 4 x 4 with an exponent. Evaluate square roots of small perfect squares and cube roots of small perfect cubes. Use square root and cube root symbols to represent solutions to equations of the form x^2 = p and x^3 = p, where p is a positive rational number.
