Two cubic roots are given below. \( \sqrt[3]{27} \) and \( \sqrt[3]{343} \) Write \( \mathrm{a} \times \mathrm{a} \times \mathrm{a} \times \mathrm{a} \times \mathrm{a} \times \mathrm{a} \) in the form of indices (b) Multiply the given two cubic roots. c) Prove that: \( \left(\frac{\mathrm{x}^{a}}{\mathrm{x}^{b}}\right)^{a+b}\left(\frac{x^{b}}{x^{c}}\right)^{b+c}\left(\frac{\mathrm{x}^{c}}{\mathrm{x}^{a}}\right)^{c+a}=1 \)

\( \left\{ \left. \begin{array} { l } { 2 x - 3 < ( x + 1 ) ^ { 2 } - x ( x - 1 ) } \\ { x + 3 - 2 x \geq 4 } \end{array} \right. \quad [ - 4 < x \leq - 1 ] \right. \)

k. \( \left[(2 a)^{2}\right]^{3} x(2 a)^{2} \)

Q8) Find the term contains \( x^{4} \) in the expansion of \( \left(x^{2}-\frac{1}{x^{2}}\right)^{12} \) according to the descending powers of \( x \), then find the ratio between the coefficient of this term and the middle term.

\[ f(x)=x^{2}-42 x+80 \] The function \( f \) is defined by the given equation. Which of the following equivalent forms of the equation displays the zeros of the function as constants or coefficients? (A) \( f(x)=x^{2}-5 x-37 x+80 \) (B) \( f(x)=(x-2)(x-40) \) (C) \( f(x)=x(x-42)+80 \) (D) \( f(x)=(x-21)^{2}-361 \)
