the root of it is 6x6 which is real easy because it equals 36.
2b=6squared, and 6x6=36
62 is 6x6. 6 Times 6 equals 36 62 = 36
6x6=36
Six times six= 36 6 times 6=36 now whats close is 7times7 but it equals 49.
36
6x6=36
6x6 = 36
There are at least two that I can think of off the top of my head. One is 6x6 and the other one is 3x12.
first use 5 times 6 = 30 than add 6 times 1 = 6 so the product of 6 times 6 is 36
6x6 in standard form = 36
6 + 6 - 6 * 6 - 6 = 6 + 6 - 36 - 6 = -30
