3^13 = 1,594,319 Your process is too long and will definitely scare certain types of learners. Here is a quicker method using ordinary Arithmetic. My Method. First, let us get the value of 3^13. 3^13 =3^(12 + 1) 3^13 =3^4●3^4●3^4●3^1 But; 3^1 = 3; and 3^4 = 81 3^13 = 3(81●81●81) 3^13 = 3(6561.81) 3^13 = 3(531,441) 3^13 = 1,594,323 3^13 - 4 = 1,594,323 - 4 3^13 - 4 = 1,594,319

3^13-4=3^13-3-1=3(3^12-1)-1
