Question : If $\left(x-\frac{1}{x}\right)=10$, what is the value of $\left(x^4+\frac{1}{x^4}\right)?$
Option 1: 10404
Option 2: 10402
Option 3: 10406
Option 4: 10400
Correct Answer: 10402
Solution : $(x-\frac{1}{x})=10$ Squaring both sides, $x^{2}+ \frac{1}{x^{2}} – 2 = 100$ ⇒ $x^{2}+\frac{1}{x^{2}}=102$ Squaring both sides again, $x^{4}+\frac{1}{x^{4}}+2=10404$ ⇒ $x^{4}+\frac{1}{x^{4}}=10402$ Hence, the correct answer is 10402.
Question : A hemispherical bowl is made of 1 cm thick steel. The inside radius of the bowl is 4 cm. The volume of the steel (in cm3) used in making the bowl is:
Option 1: $40\frac{2}{3}\pi$
Option 2: $27\frac{1}{3}\pi$
Option 3: $41\frac{1}{3}\pi$
Option 4: $35\frac{1}{3}\pi$
Correct Answer: $40\frac{2}{3}\pi$
Solution : Given: Inner radius $(r)$ = 4 cm Outer radius $(R)$ = 4 + 1 = 5 cm According to the question, The volume of steel used = $\frac{2}{3}×\pi (R^3-r^3)$ = $\frac{2}{3}×\pi (5^3-4^3)$ = $\frac{2}{3}×\pi (125-64)$ = $\frac{2}{3}×\pi ×61$ = $\frac{122}{3}×\pi$ = $40\frac{2}{3}\pi\ \text{cm}^3$ Hence, the
