To continue the exponent rules, raising a power to another power is the same as multiplying the exponents together. You can also rewrite the expression on the right to mirror the one on the left.ħ. Similar to the multiplication rule above, if you have the same base number raised to different powers being divided, you can subtract the exponents. In this case, if you have the same base number raised to different powers being multiplied together, you can add the exponents together. #Sat formula sheet how toKnowing how to manipulate exponents in a variety of ways will help you tremendously on the SAT, especially the no-calculator portion. #Sat formula sheet plusNote that you will get two answers because there is the plus and minus sign in the numerator. You need the quadratic to be in the form \(y=ax^2 bx c\), and then you simply plug the coefficients and constants into the formula. The quadratic formula helps you find the roots of a quadratic equation (parabola) if you can’t easily factor it. Take the values of the coordinates and plug them into this formula to find the distance, and be sure to apply the squares and the square root at the right step. The distance formula is derived from the Pythagorean Theorem (covered later in this post) and it’s useful for quickly finding the distance between two points. The values of \(h\) and \(k\) give you the coordinates of the vertex, \((h,k)\). However, you should be able to recognize vertex form and convert quadratics to this form for the SAT. You may be more familiar with a quadratic in its factored form, or in the form \(y=ax^2 bx c\). For example, if we have the equation \(y=2x 4\), then the slope is \(2\) and the y-intercept is \((0,4)\). The \(m\) in the equation represents the slope of the equation, and the \(b\) represents the y-value of the y-intercept.

Calculate your admissions chances right now. We’ve categorized these formulas to help you focus your preparation, and we’ve provided a quick review of what each concept is. While there’s always more than one way to reach the right answer, being able to quickly remember these math facts will help you answer questions more efficiently and minimize careless mistakes. If you don’t do any studying for the SAT, you’ll take longer to recall certain helpful formulas and concepts. This is part of what makes the SAT challenging: since it draws on many different types of math, you need to get out of the high school math mindset (where you only remember what you’ve learned the last month or so to ace the test) and review the math you’ve learned over the years. While you probably learned these formulas at some point, it may have been a while since you’ve had to use them. The SAT covers a wide range of math-from as early as elementary school all the way to senior year of high school. Have you ever been stumped on a math test question, only to realize how simple it was when you later reviewed your test? That’s exactly what happens to many students who take the SAT.
