This is the second part of our guide to SAT Number Properties. Here, we focus on the algebraic tools you'll need for the "Passport to Advanced Math" domain, including the laws of exponents and the crucial skill of working with radicals (square roots).
Start with the core definitions, including positive, negative, zero, and fractional exponents (roots). Build an intuitive understanding with our interactive explorer.
Master the essential rules for manipulating exponents, such as the product, quotient, and power rules. These are critical for simplifying complex expressions on the SAT.
Learn the essential techniques for simplifying radicals (e.g., √72) and combining like terms, a common task in the no-calculator section.
Memorize and apply the most important algebraic formulae, like (a+b)² and a²-b², which are frequently used to manipulate and simplify expressions on the SAT.
