1. The problem asks which expression is equivalent to 100,000. 2. Recall that powers of 10 represent 10 multiplied by itself a certain number of times: $$10^n = \underbrace{10 \times 10 \times \cdots \times 10}_{n \text{ times}}$$. 3. To find the power of 10 equal to 100,000, write 100,000 in exponential form. 4. Count the number of zeros in 100,000: there are 5 zeros. 5. Therefore, $$100,000 = 10^5$$. 6. Checking the options, option B is $$10^5$$, which matches 100,000. Final answer: B 10^5
