Step 1:Let's solve this step by step:
Step 2:: Understand the meaning of $5^{1 / 2}$
- $5^{1/2}$ represents the square root of 5
- This means we are looking for a number that, when multiplied by itself, equals 5
Step 3:: Simplify $5^{1 / 2}$
- $$5^{1/2} = \sqrt{5}
- This is a number between 2 and 3 (since 2^{2} = 4 and 3^{2} = 9)
Step 4:: Evaluate the given options
- D. $$15 \cdot 3 = 45$$ - This is also not equal to $$\sqrt{5}
- B. 5^{3} = 125 - This is much larger than \sqrt{5}
Step 5:: Recognize the correct answer
- None of the given options are equal to $$5^{1/2}
- However, the question requires selecting an answer
Final Answer
There is an error in the problem, as none of the given options are equal to 5^{1 / 2}.
