Question : If $a^2+1=9a$ and $a\neq0$, then the value of $a^2+\frac{1}{a^2}$ is:
Option 1: 81
Option 2: 18
Option 3: 79
Option 4: 83
Correct Answer: 79
Solution : Given: $a^2+1=9a, a\neq0$ Dividing both sides by $a$, we get $a+\frac{1}{a}=9$ Squaring both sides, we get $a^2+\frac{1}{a^2}+2×a×\frac{1}{a}=81$ ⇒ $a^2+\frac{1}{a^2}=81-2$ $\therefore a^2+\frac{1}{a^2}=79$ Hence, the correct answer is 79.

Question : The value of $15 \div 8-\frac{5}{4}$ of $\left(\frac{8}{3} \times \frac{9}{16}\right)+\left(\frac{9}{8} \times \frac{3}{4}\right)-\left(\frac{5}{32} \div \frac{5}{7}\right)+\frac{3}{8}$ is:
Option 1: 0
Option 2: 1
Option 3: 2
Option 4: 3
Correct Answer: 1
Solution : Given: $15 \div 8-\frac{5}{4}$ of $\left(\frac{8}{3} \times \frac{9}{16}\right)+\left(\frac{9}{8} \times \frac{3}{4}\right)-\left(\frac{5}{32} \div \frac{5}{7}\right)+\frac{3}{8}$ $=\frac{15}{8}-\frac{5}{4}\text{of}\frac{3}{2} +\frac{27}{32}-\frac{7}{32}+\frac{3}{8}$ $=\frac{15}{8}-\frac{15}{8} +\frac{27}{32}-\frac{7}{32}+\frac{3}{8}$ $=\frac{27}{32}-\frac{7}{32}+\frac{3}{8}$ $=\frac{27-7+12}{32}$ $=\frac{32}{32}$ $=1$ Hence, the correct answer is 1.
