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 $\frac{1}{9}$

m+4n=8
m-n=-2

Eliminating m gives;
5n=10
n=2
Replacing for n in the first equation;
m+4(2)=8
m=8
Answer;

Answer:

$x>-5$

Step-by-step explanation:

$\frac{-1}{5} x+1$

Subtract 1 from both sides

$\frac{-1}{5} x+1-1$

Simplify

$\frac{-1}{5} x$

Multiply both sides by -1, which reverses the inequality also

$\frac{-1}{5} x(-1)>1(-1)$

Simplify

$\frac{1}{5} x>-1$

Multiply both sides by 5

$5*\frac{1}{5} x>5(-1)$

Simplify

$x>-5$
