What is `2^8?`
An exponent represents the number of times the base is to be multiplied by itself.
`2^8 = 2*2*2*2*2*2*2*2`
Since 2 x 2 = 4, there are 4 pairs of 2x2
`2^8 = 4^4`
`4^4 = 4*4*4*4`
Since 4 x 4 = 16, there are 2 pairs of 4x4
`2^8 = 4^4 = 16^2`
`16^2 = 16*16`
`2^8 = 4^4 = 16^2 = 256`
The solution is `2^8 = 256.`

The value of 2 raised to the 8th power has to be determined.
`2^8 = (2^2)^4 = 4^4 = (4^2)^2 = 16^2 = 256`
2 raised to the 8th power is 256

2^8 = 16^2 = 256.
2 to the power of 8 is therefore 256.

2 raised to the 8th power?
Power is the multiplicative property of a number, it is one which shows that how many times a number is to be multiplied by itself, i.e when it is 2^2 then 2 will multiplied by itself once i.e 2*2, when it is 2^5 then 2 will be multiplied by itself 4 times, i.e. 2*2*2*2*2, similarly when it 2^8 then the number 2 will be multiplied by itself 7 times, i.e. 2*2*2*2*2*2*2*2, the answer to which is 256.
` ``2^8 = 256 Answer.`

2^8 = 2·2·2·2·2·2·2·2
which equals to 256

2⁸ is basically multiplying 2 eight times
2 X 2 X 2 X 2 X 2 X 2 X 2 X 2
2 X 2 = 4
4 X 2 = 8
8 X 2 = 16
16 X 2 = 32
32 X 2 = 64
64 X 2 = 128
128 X 2 = 256
= 256 which is your answer

2^8th power is the same as multiplying 2, 8 times
2*2*2*2*2*2*2*2= 256

`2^8` =2*2*2*2*2*2*2*2=4*2*2*2*2*2*2=4*4*2*2*2*2=4*4*4*2*2=4*4*4*4=16*4*4= 16*16=256

2 raised to the 8th is like `2xx2xx2xx2xx2xx2xx2xx2`
so do the one by one:
`2xx2 = 4`
`4xx2 = 8`
`8xx2 = 16`
`16xx2 = 32`
`32xx2 = 64`
`64xx2 = 128`
`128xx2 =256`
so `2^8 = 256`

2^8=
2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 =
2 * 2 = 4
4 * 2 = 8
8 * 2 = 16
16 * 2 = 32
32 * 2 = 64
64 * 2 = 128
128 * 2 = 256
