properties of exponents - ANSWER- whole number exponents: b^n = b • b • b... (n times) - zero exponent: b^0 = 1; b ≠ 0 - negative exponents: b^-n = 1/(b^n); b ≠ 0 - rational exponents (nth root): ^n√(b) = 1/(b^n); n ≠ 0, and if n is even, then b ≥ 0 - rational exponents: ^n√(b^m) = ^n√(b)^m = (b^(1/n))^m = b^(m/n); n ≠ 0, and if n is even, then b ≥ 0 operations with exponents - ANSWER- multiplying like bases: b^n • b^m = b^(n + m) (add exponents) - dividing like b...

second degree equations - ANSWER -solved by factoring or the quadratic formula absolute value - ANSWER -equivalent to two equations without the absolute value sign > e.g. |x + 3| = 7 → +(x + 3) = 7 or -(x + 3) = 7 solving linear inequalities - ANSWER -can be treated like a linear equation, however, when multiplying or dividing both sides of an inequality by negative numbers requires the inequality sign to be reversed solving absolute value inequalities - ANSWER -- with absolute va...
