Evaluate the following expression. 3^-2

Crazy boy [7]

Answer: The simplified form is $\frac{1}{9}$

Step-by-step explanation:

Since we have given that

$3^{-2}$

As we know the "Exponential law":

$a^{-1}=\frac{1}{a^m}$

So, it becomes

$3^{-2}=\frac{1}{3^2}$

Now, at last it becomes,

$3^{-2}=\frac{1}{3\times 3}=\frac{1}{9}$

Hence, the simplified form is $\frac{1}{9}$

Which of the following represents the series ?

aleksklad [387]

The denominator in each term of the series is a square number, but neither $n-6$ nor $n^2+1$ are squares. So none of (1), (2), and (4) can be correct. The answer must be (3).
