log (base 8) 2 + log (base 4) 2 = ?
For this, you just need to figure out the exact value of each. If you can't use a calculator, you should hope that the values are clean (like they are in this case)
log (base 8) 2 = x
8^x = 2
2^(3x) = 2^(1)
3x = 1
x = 1/3
log (base 8) 2 = 1/3
similarly you can find log (base 4) 2 = 1/2
