M2/n2 is equivalent to _____.

tankabanditka [31]

Answer:

$\frac{m^2}{n^2}$ is equivalent to $m^2 \cdot n^{-2}$

Step-by-step explanation:

Using exponent rules:

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

Given the expression:

$\frac{m^2}{n^2}$

⇒ $\frac{m^2}{n^2} = m^2 \cdot \frac{1}{n^2}$

Apply the exponent rule, we have;

$m^2 \cdot n^{-2}$

Therefore, the given expression $\frac{m^2}{n^2}$ is equivalent to $m^2 \cdot n^{-2}$

Azul bought 10 reams of paper at the tore for a total cost of 84$ the tax on the purpose was 4$ what equation could be used to r

tankabanditka [31]

Answer:

The equation $10x+4=84$ could be used to represent this situation.

Step-by-step explanation:

Given:

Azul bought 10 reams of paper at the store for a total cost of $84 the tax on the purpose was $4.

Now, to find the equation that could be used to represent this situation.

Let the cost of a ream of paper be $x.$

Total reams of paper = 10.

The tax on the purpose = $4.

The total cost = $84.

Now, to write an equation to represent this situation:

$10\times x+4=84$

$10x+4=84$

Therefore, the equation $10x+4=84$ could be used to represent this situation.
