If \(\frac{a}{b}=\frac{b}{c}=\frac{c}{d},\text{ then }\frac{a}{d}\) , then terms of b and c is equal to:
\(\left(\frac{b}{c}\right)^3\)
\(\left(\frac{b}{c}\right)^2\)
\(\left(\frac{b}{c}\right)^{1.5}\)
\(\left(\frac{b}{c}\right)^{0.5}\)
Simplify \(\frac{10^2 \text{ of } \left(\frac15\right)^3 \div \frac14 \times 4 - \frac25 \text{ of } 15}{\frac45 \left(5 \div 5 \text{ of } 12 + \frac16\right)}\)
\(-\frac{65}{73}\)
34
\(-\frac{147}{73}\)
\(-\frac{78}{73}\)
