(12)5 ——(0.5)5 (\frac{1}{2})^5\text{ }_{——}(0.5)^5

Video Solution

Solution Steps

00:09 Let's find out which number is larger.
00:15 To compare, first, change the fraction into a decimal.
00:20 It looks like both values are equal.
00:23 And that's how we solve the question. Great job!

Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Recognize that 12\frac{1}{2} is equivalent to 0.50.5.

  • Step 2: Evaluate both expressions using this equivalence.

  • Step 3: Conclude based on the equality of the expressions.

Now, let's work through each step:
Step 1: It's important to understand the equivalence between 12\frac{1}{2} and 0.50.5. As a fraction, 12\frac{1}{2} is equal to the decimal 0.50.5.
Step 2: We apply the power to each base: (12)5(\frac{1}{2})^5 and (0.5)5(0.5)^5. Due to their equivalence, (12)5(\frac{1}{2})^5 is necessarily equal to (0.5)5(0.5)^5.
Step 3: Since both expressions compute to the same value because their bases are identical (12=0.5\frac{1}{2} = 0.5), the two expressions are equal.

Therefore, the solution to the problem is= = .
