C. 17 7
Step-by-step solution
array ll & Let 2 ⁻¹ ( 1 5 )=x & ⁻¹ ( 1 5 )= x 2 & x 2 = 1 5 & Using & 2 = 2 1- ^2 & x= 2 ^ x 2 1- ^2 x 2 array aligned & x= 2 1 5 1- 1 25 & x= 5 12 ...(i) aligned aligned & Consider (2 ⁻¹ ( 1 5 )+ 4 ) & = (x+ 4 ) & = x+ 4 1- x 4 & = 5 12 +1 1- 5 12 & = 17 12 7 12 = 17 7 aligned
