Question 23 Simplify this expression, writing the answer with a rational denominator. \( \frac{1}{\sqrt{3}} \times \frac{1}{\sqrt{3}-1}=\frac{\square+\sqrt{3}}{\square} \)

3. Uis tiene el triple de dinero de maria menos \( \$ 1,0000 \) si entre ambos tienen \( \$ 110,000 \) ¿Cuanto dinero tiene en tatal maria?

\( 4 x^{2}+k x+5=0 \) has roots whose difference is \( \frac{1}{4} \)

will be cqual, if either \( b=0 \), or \( a^{3}+b^{2}+c^{3}-3 a b c-0 \). If \( a, b, c \) arc rational and \( a+b+c=0 \), show that the roots of \( (b+c-a) x^{2}+(c+a-b) x+ \) \( (a+b-c)=0 \) are rational.

Which is equivalent to \( \frac{x^{3}}{\sqrt{x}} \) ? A. \( x^{3 / 2} \) B. \( x^{2} \) C. \( x^{5 / 2} \) D. \( x^{7 / 2} \) E. \( x^{6} \)
