Insert the corresponding expression:
(86)2=
To solve this problem, we'll compute (86)2 using the rule for powers of a fraction:
- Step 1: Identify the numerator and denominator: a=6 and b=8.
- Step 2: Apply the formula (ba)n=bnan with n=2.
- Step 3: Calculate an=62.
- Step 4: Calculate bn=82.
Now, let's carry out the calculations:
Step 3: 62=36.
Step 4: 82=64.
Therefore, (86)2=6436.
We compare 6436 with the given answer choices:
- Choice 1: 1612 is not equal.
- Choice 2: 646 is not equal.
- Choice 3: 6436 matches our result.
- Choice 4: 836 is not equal.
Therefore, the correct answer is 6436, which matches Choice 3.
