1. The problem is to evaluate the expression $10^5$. 2. The expression $10^5$ means 10 raised to the power of 5, which is multiplying 10 by itself 5 times. 3. Using the formula for exponents: $$a^n = \underbrace{a \times a \times \cdots \times a}_{n \text{ times}}$$ 4. So, $$10^5 = 10 \times 10 \times 10 \times 10 \times 10$$ 5. Calculate step-by-step: $$10 \times 10 = 100$$ $$100 \times 10 = 1000$$ $$1000 \times 10 = 10000$$ $$10000 \times 10 = 100000$$ 6. Therefore, the value of $10^5$ is $100000$.
