To find 3 times any number, Maria doubles the number and then adds the number again. a Show how Maria would solve \( 3 \times 6 \). \( \begin{array}{l}2 \times 6=12 \\ 12+6=18\end{array} \)

The line \( y=m x+c \) is a tangen to the ellipse \( \frac{x^{2}}{a^{2}}+\frac{y^{2}}{b^{2}}=1 \) (a) Obtain an expression for \( s \) in terms of \( a, b \), and \( m \).

e \( \left[\left(16^{4}+12^{4}-8^{4}\right): 4^{4}-\left(2^{2}\right)^{2}\right]-\left(5^{2}+7^{2}\right)+\left(3^{2}+2^{2}\right) \cdot 2^{2}-\left[2^{2} \cdot\left(2^{2}\right)^{3}+3^{3}\right] \) \( 27\left[21: 7 \cdot 4-\left(2^{3}-2^{2}\right)^{0}+26 \cdot 2^{2}: 13-\left(6-2^{2}-9: 3^{2}\right)\right]:\left[6 \cdot 4-2^{4}+\left(32: 2^{4}\right]\right. \)

\( ( \frac { x ^ { 4 } - 2 x ^ { 3 } + x ^ { 2 } } { x ^ { 2 } } ) \quad ( \frac { 9 y ^ { 3 } - 3 y ^ { 2 } + 6 y } { 3 y } ) \quad ( \frac { 12 b ^ { 4 } - 6 b ^ { 3 } + 3 b ^ { 2 } } { 3 b ^ { 2 } } ) \)
