Given that $\sqrt{5}$ =2.24, then the value of $\frac{3\sqrt{5}}{2\sqrt{5}-0.48}$ is
1). 0.168
2). 1.68
3). 16.8
4). 168
1. Let $\sqrt[3]{a}$ = $\sqrt[3]{26}+\sqrt[3]{7}+\sqrt[3]{63}$ , then
2. If $3^{x+y}$=81 and $81^{x-y}$=3, then the value of x is
4. Given $\sqrt{2}$ =1.414. The value of $\sqrt{8}+2\sqrt{32}-3\sqrt{128}+4\sqrt{50}$ is
5. $(\sqrt{8}-\sqrt{4}-\sqrt{2})$ equals :
8. The simplified value of $(0.2)^{3}\times 200+ 2000 of (0.2)^{2}$ is
