The SAT knows you know your basic exponent rules. But it also knows how to still trick you. In the midst of the test, stressed out and trying to finish before the proctor yells out the dreaded “stop”, you might flub something. Do you add exponents if you multiply (only if the bases are the same), and what about an exponent raised to another exponent (hint: multiply). Can you add exponents? What if the bases are the same? (A resounding “not exactly” to the last two questions).
So, let’s see if you can handle the exponents in the video question. Will you get trapped? Or will you rely on your exponent knowledge (and some logic) to get the right answer?
