Oh, I see what you did now. After taking the common factor you are left with the two equations. Then it is simply multiplication.chetanojha wrote:Take 2^5 and 3^5 common
2^5(1+1)+3^5(1+1+1) = 2*2^5+3*3^5 =2^6+3^6
So simple, yet so hard to figure it out when stuck.
Thanks!!

When you have to add exponents, always factor
2^5(1 + 1) = 2^5(2) which is the same as 2^5(2^1).
With the rule
x^x * x^y = x^x + y
2^5(2^1) = 2^5+1 = 2^6
3^5(1 + 1 + 1) = 3^5(3) which is the same as 3^5(3^1)
With the rule
x^x * x^y = x^x + y
3^5(3^1) = 3^5 + 1 = 3^6
2^5(1 + 1) = 2^5(2) which is the same as 2^5(2^1).
With the rule
x^x * x^y = x^x + y
2^5(2^1) = 2^5+1 = 2^6
3^5(1 + 1 + 1) = 3^5(3) which is the same as 3^5(3^1)
With the rule
x^x * x^y = x^x + y
3^5(3^1) = 3^5 + 1 = 3^6
