Domain: Expressions and Equations Cluster: Work with radicals and integer exponents. 1. Know and apply the properties of integer exponents to generate equivalent numerical expressions. _x_ Full For example, 32 x 3-5 = 3-3 = 1/33 = ___ Partial 1/27. ___ No 3rd 2. Use square root and cube root symbols to represent solutions to equations of the form x2 = p and x3 = _x_ Full p, where p is a positive rational ___ Partial number. Evaluate square roots of ___ No 3rd small perfect squares and cube roots of small perfect cubes. Know that √2 is irrational. 3. 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 _x_ Full the other. For example, estimate the ___ Partial population of the United States as 3 x ___ No 3rd 108 and the population of the world as 7 x 109, and determine that the world population is more than 20 times larger.
