4 to the 8th power is 65,536.
8-4 is equivalent to 0.000244140625.
I assume you mean the last digit. The idea is to find a pattern: 8 to the power 1 ends with 8 8 to the power 2 ends with 4 8 to the power 3 ends with 2 (to figure this out, I just multiplied 4 x 8) 8 to the power 4 ends with 6 (once again, multiply the last digit of the previous power x 8) 8 to the power 5 ends with 8 8 to the power 6 ends with 4 ... As you can see, it all repeats, with a period of 4. Therefore, any exponent that is a multiple of 4 will end with 6. Find the nearest multiple of 4 that is smaller than 2015, then continue calculating - always with the last digit.

4^8 / 4^6 is equal to 16.
It is: 8^4 times 8^5 = 134217728
8 to the power (2/3) equals 4.
4 to the fourth power times 8 to the ninth power = 34,359,738,368
8^4 = 8*8*8*8 = 4096

It is 4^8 which means 4 to the power of 8
-8 ^ 4 = -8 * -8 * -8 * -8 = 4,096
8^4 = 4096.
-12 x8 y8 / 3x4 y2 = -4 x4y6 First: divide -12 by 3 which equals -4 Second: divide x to the power of 8 by x to the power of 4 by subtracting the two powers ( 8-4 ) which will equal x to the power of 4 Third: divide y to the power of 8 by y to the power of 2 by subtracting the two powers ( 8-2 ) which will equal y to the power of 6
2 to the power of 3 equals 8...2 times 2 is 4 and 4 times 2 is 8.
