10. Carolyn says that point \( A \) and point \( B \) represent opposite integers. a. What is the opposite of the integer represented by point \( A \) ? By point \( B \) ?

Evaluate the expression without using a calculator In \( e^{4} \) \( \ln ^{4}=\square \)

\( \left. \begin{array} { l } { \frac { 3 } { 4 } - \frac { 2 } { 5 } = \frac { ( 5 ) ( 3 ) } { ( 5 ) ( 4 ) } - \frac { ( 4 ) ( 2 ) } { ( 4 ) ( 5 ) } = \frac { 15 } { 20 } - \frac { 8 } { 20 } = \frac { } { 20 } } \\ { \frac { 1 } { 4 } + \frac { 1 } { 2 } = \frac { 1 } { 4 } + \frac { ( L ) ( 1 ) } { ( ) ( 2 ) } = \frac { 1 } { 4 } + \frac { 2 } { 4 } = - } \end{array} \right. \)

Evalúa \( -a+(-b) \), donde \( a=6.05 \) y \( b=3.611 \). \( \square \)

) \( \frac{7}{6}+\frac{2}{4}+\frac{1}{12}= \)
