The answer is 4 because 4 you can break it into 2 times 2 and 2 is prime so thats the prime #s of 4 and for 84 you can do 42 times 2 then for 42 2 times 21 and then three times 7 = 21 so your prime factors of 84 are 237and 2 and the prime numbers of 4 is 2 and 2 so is you line those #s up there is…

still 64 same as 2 times 4 and times 8 and so on ... like 6 = 1 x 2 x 3 = 2 x 3 x 1 = 3 x 1 x 2 as they are all times so the order does not matter same for adding

To find the answer, one does 4x4 to get your 4 squared. Then times that by 2. Then times that 4 times. It should look like this: (42x2)4 (16x2)4 (32)4 32x32x32x32 1,048,576
