Raising an exponent to a power and practice problems.
If you’ve been following along with the Math Dude podcast you’ll know that we’ve spent a lot of time talking about exponents: What positive exponents are, what negative exponents are, how to multiply exponents, how to divide exponents, and this week we talked about how to raise an exponent to an exponent. After learning all of that you should now be able to figure out what expressions like (255)5 and ((33)3)3 are equal to. All you need to know to answer these questions is that you can raise an exponent to a power simply by multiplying the exponents. In other words, (3a)b = 3a×b for any value of the base number (i.e., the base doesn’t have to be 3).
