We use the power law for multiplication within parentheses:
We apply it to the problem:
Therefore, the correct answer is option b.
Note:
From the formula of the power property mentioned above, we understand that it refers not only to two terms of the multiplication within parentheses, but also for multiple terms within parentheses.
\( 112^0=\text{?} \)
Be careful with notation! Writing 345 means three hundred forty-five, not 3×4×5. The multiplication symbols matter! You can calculate (3×4×5)⁴ = 60⁴, but 345⁴ is completely different.
Absolutely! The power rule works with any number of factors inside the parentheses.
Yes! Calculate each power separately: , , , then multiply: 81×256×625 = 12,960,000.
If you see (no parentheses), only the 5 gets the exponent: . Parentheses make all the difference!
You can multiply inside first: , but for multiple choice questions, recognizing the power rule pattern is often faster than calculating the final number.
