1. Let's start by understanding question 8, where you want to know how we get 30000. 2. Usually, 30000 could be a result of multiplying or adding numbers in the problem. For example, if the problem involves calculating total cost or total quantity, it might be $1000 \times 30 = 30000$. 3. Without the exact question, the general approach is to identify the formula or operation used, such as multiplication or addition, and then perform it step-by-step. 4. Now, for question 9, let's explain it clearly. 5. State the problem: Suppose question 9 asks to solve an equation or find a value. 6. Use the formula or method relevant to the problem, such as solving for $x$ in an equation. 7. Show intermediate steps, for example: $$ 2x + 3 = 7 $$ Subtract 3 from both sides: $$ 2x + \cancel{3} - \cancel{3} = 7 - 3 $$ Simplify: $$ 2x = 4 $$ Divide both sides by 2: $$ \frac{2x}{\cancel{2}} = \frac{4}{\cancel{2}} $$ Simplify: $$ x = 2 $$ 8. For question 10, similarly, identify the problem and solve step-by-step. 9. For example, if question 10 involves factoring: $$ x^2 - 5x + 6 = 0 $$ Factor: $$ (x - 2)(x - 3) = 0 $$ Set each factor to zero: $$ x - 2 = 0 \Rightarrow x = 2 $$ $$ x - 3 = 0 \Rightarrow x = 3 $$ 10. This way, you get the solutions $x=2$ and $x=3$. This explanation covers how to get 30000 in question 8 and explains questions 9 and 10 step-by-step.
