Question

( A=log _{2} log _{2} log _{4} 256+2 log _{sqrt{2}} 2 )
( A=log _{2} log _{2} log _{4} 4^{4}+2 log _{(2) 1 / 2} 2^{2} )
( A=log _{2} log _{2}left(4 times frac{left.log _{4} 4right)}{4}+frac{2}{1 / 2} log _{2} 2right. )
( A=log _{2} log _{2} 4+4 times 1 )
( A=log _{2} log _{2}(2)^{2}+4 times 1 )
( A=log _{2}left(2 times log _{2} 2right)+4 )
( A=log _{2} 2+4 )
( A=1+4=5 )
