What would the sum of -18-(-12) be?

Mademuasel [1]

-18-(-12)=-6
Since there is two negative sign, it turns into positive meaning the -12 becomes positive 12 and the -18 stays same. So -18+12=-6 because 18 is bigger than 12 and it's negative so the final answer should be negative.
Hint: when you see two negative sign just turn them into plus sign.

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 $\frac{1}{9}$
