in a problem like n4=625 you need to do a mult-step equations In the example, 4log n = log 625 log n = (log 625)/4 n = 10^[(log 625)/4] = 5 Although this particular answer is obvious, you could also solve n5=625, or any other power of n, which isn't, using this method. hope that it is helpful to you!

5 x 5 x 5 x 5 = (5)4(It works out to be 625.)
