Without using tables, evaluate \((343)^{\frac{1}{3}} \times (0.14)^{-1} \times (25)^{-\frac{1}{2}}\)
-
10
- 12
- 8
- 7
The correct answer is: A
Explanation
\((343)^{\frac{1}{3}} \times (0.14)^{-1} \times (25)^{-\frac{1}{2}}\)
= \(\sqrt[3]{343} \times (\frac{14}{100})^{-1} \times (\sqrt{25})^{-1}\)
= \(7 \times \frac{100}{14} \times \frac{1}{5}\)
= 10.
