Hi shakticnb,   Certain Quant questions on the GMAT are just about 'organizing' the information in a specific way. If you find yourself getting confused by a prompt, think about how you might change the way that the information is presented to you.   Here, for example, we're asked for....   6^5 + 6^5 + 6^5 + 6^5 =   Now, the GMAT doesn't really expect us to calculate this sum (but we could if we had to), but we are expected to find a way to organize this information... If, instead of all of those exponents, we had...   X + X + X + X =   What would the sum be?   Clearly, it would be 4(X) = 4X.....since we're just combining 'like' terms. Take that same idea with this prompt and you have...   6^5 + 6^5 + 6^5 + 6^5 =   6(6^5)   This can be re-written as...   (6^1)(6^5)   ...and now we can use exponent rules; since we're MULTIPLYING 'bases' that are the same, we ADD the exponents...   (6^1)(6^5) = 6^6   Final 6^6nswer:   6^6
