For the Production Function $Y = z K 0.36 N 0.64$

For the production function, $Y = z K 0.36 N 0.64$ , if measured output is $\hat { Y }$ , measured capital input is $\hat { K }$ , and measured labour input is $\hat { N }$ , then the Solow residual would be equal to

A) $\frac { \hat { K } ^ { 0.36 } \hat { N } ^ { 0.64 } } { \hat { Y } }$ .
B) $\frac { \hat { K } ^ { 0.36 } } { \hat { N } ^ { 0.64 } } \times \hat { Y }$ .
C) $\frac { \hat { Y } } { \hat { K } ^ { 0.36 } \hat { N } ^ { 0.64 } }$ .
D) $\frac { \hat { N } 0.64 } { \hat { K } 0.36 } \times \hat { Y }$ .
E) $\frac { \hat { K } 0.36 } { \hat { N } ^ { 0.64 } } \times z \hat { Y }$ .
