Given series: 9,2, 6561, 43046721
We need to determine the missing number in the series.
First, we note that $43046721 = 6561 \cdot 6561 = 6561^{2}$ and thus we suspect that each term is the square of the next term.
Let us determine the square of the first term 9:
$9^{2} = 81$
Thus we suspect that the missing term is 81, which is confirmed by the fact that $81^{2} — 6561$ .

Answer: 81Explanation:To find the missing number in the series 9,?,6561,43046721, we can look for a pattern or relationship among the given numbers. Let&#039;s examine the given sequence more closely.The first number, 9, can be expressed as 32. The second number in the sequence is the missing number, which we&#039;ll represent as x. The third number, 6561, can be expressed as 38. The fourth number, 43046721, can be expressed as 316.It appears that the exponent of 3 is increasing by a factor of 2 with each successive number in the sequence. Therefore, we can deduce that the missing number should be expressed as 34, which is equal to 81.Thus, the missing number in the series 9,?,6561,43046721 is 81.

The first number, 9, can be obtained by taking the square of 3 (

3^{2}

= 9).
The second number, 81, can be obtained by taking the square of 9 (

9^{2}

= 81).
The third number, 6561, can be obtained by taking the square of 81 (

81^{2}

= 6561).
The fourth number, 43046721, can be obtained by taking the square of 6561 (

6561^{2}

= 43046721).
Therefore, the missing number in the series can be obtained by taking the square of 81 (

81^{2}

).
Hence, the missing number in the series is

81

.

Solution:9,&amp;nbsp;?,&amp;nbsp;6561,&amp;nbsp;43046721We observe that each number in the series is the result of raising the previous number to a certain power. Specifically, each number is obtained by squaring the previous number. Using this pattern, we can find the missing number.The first number, 9, is raised to the power of 2 to obtain the second number. Similarly, the second number is raised to the power of 2 to obtain the third number. Applying this pattern to the third number, we raise it to the power of 2 to find the fourth number.Therefore, the missing number can be obtained by squaring the third number:x=65612
