anonymous · Answer

m^4

anonymous · Answer

how did you get that i got m^2

anonymous · Answer

2^8=256, the square root of 258 =16
2^4=16

anonymous · Answer

so a square root is just m^1/2 power so if you have the square root of m^16 you just need to multiply the two exponents together (1/2)*(16)=8

anonymous · Answer

but 2^ is 256 not 258

anonymous · Answer

@Moose23 is it ok if you help me in other questions?
