212 / बीजगणित (Algebra) 24. यदि \( 4,2 x-4, \ldots \ldots, 64,21 x+2 \) एउटा गुणोत्तर अनुक्रमको पदहरू भए, If \( 4,2 x-4, \ldots \ldots, 64,21 x+2 \) are the terms of geometric sequence (i) \( x \) को मान पत्ता लगाउनुहोस् । (Find the value of \( x \).) (ii) समान अनुपात पत्ता लगाउनुहोस् । (Find the common ratio.) (iii) चौथो पद पत्ता लगाउनुहोस् । (Find the value of fourth term.)

Determine the value(s) of k for which the equation \( \frac{1}{\mathrm{k}}=\mathrm{x}^{2}-\mathrm{x}+1 \) where \( \mathrm{k} \neq 0 \) has real roots.

\( f(x)=\frac{\sqrt{x+2}}{3-3 x^{2}} \), for which values of \( x \) \( (x) \) non real

95 If \( \frac{\log x}{\log 3}+\frac{\log x}{\log 9}+\frac{\log x}{\log 27}=22 \), then \( x=\ldots \ldots \ldots \ldots \ldots \) \( \begin{array}{llll}\text { (a) } 3^{2} & \text { (b) } 3^{9} & \text { (c) } 3^{12} & \text { (d) } 3^{27}\end{array} \)

Sbuve that \( (2 \sqrt{2})^{5}=32 \sqrt{2} \)

Utiliza logaritmos para resolver: \( 5^{x} = 125 \).
