When multiplying terms, you add the exponents. when dividing terms, you subtract exponents. With exponents of exponents, you multiply. For example, 3. (3^2)^3 = 3^2 * 3^2 * 3^2 = 3^6

Try to break up the problem into smaller pieces. For example, 54+5=59, so can you make 41 from 3,5,6,2? If not, try using 54-5=49. See if you can make 51 from 3,5,6,2. You are allowed to use exponents, for example, 6^2=36.
