Question

9^8 x 729 -------- 81^5

Answer 1

9⁸·729/81⁵=9⁸·9³/9¹⁰=9¹¹/9¹⁰=9

Answer 2

Let's break down the expression step by step:

$9^8$ means $9$ raised to the power of $8$, which is $43046721$. $729$ is already $729$. $81^5$ means $81$ raised to the power of $5$, which is $4437053121$.

Now, substituting these values back into the expression:

$\frac{9^8 \times 729}{81^5} = \frac{43046721 \times 729}{4437053121}$

Calculating the numerator:

$43046721 \times 729 = 31384283781609$

So the expression becomes:

$\frac{31384283781609}{4437053121} \approx 7053960.095$

Therefore, $9^8 \times 729 \div 81^5$ is approximately $7053960.095$.
