( x=log _{2} sqrt{56+sqrt{56+sqrt{56}-}} ) 3 ( 2^{x}=sqrt{5 b+sqrt{5 b+sqrt{56+cdots}}} ) ( partial^{x}=sqrt{5 b+left(2^{x}right)} ) S ( left(Q^{x}right)^{2}=5 b+2^{x} ) ( -12left(2^{x}right)^{2}-2^{x}-56=0 ) & ( left(2^{x}right)^{2}-8left(2^{x}right)+7left(2^{x}right)-56=0 ) & ( 2^{x}left(2^{x}-8right)+7left(2^{x}-8right)=0 ) ( therefore quad 2^{x}=-7 quad x ) ( int_{theta}^{2^{x}=8}{2 x^{2}=3} )
