What should come in place of the question mark $(?)$ in the following expression?
$(674.87 + 59.98) \div 35.02 = ?$

Evaluate $\frac{0.53 \times 0.53 - 2 \times 0.53 \times 0.41 + 0.41 \times 0.41}{0.53 - 0.41}$

If $(x+\frac{1}{x})^{2}=3$,then the value of $(x^{72}+x^{66}+x^{54}+x^{36}+x^{24}+x^{6}+1)$ is

If a man spends $\frac{5}{6}$ part of his money and,again earns $\frac{1}{2}$ part of the remaining money,what part of his money is with him now?

If $x^{2}+3x+1=0,$ then the value of $x^{3}+\frac{1}{x^{3}}$ is

The simplification of $1+\frac{1}{1+\frac{1}{1-\frac{2}{3}}}$ yields the result
