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

Three added to eight times a number is the same as three times the value of two times the number -1

emmainna [20.7K]

Answer:

The number x is -3

Therefore x=-3

Step-by-step explanation:

Given problem is "Three added to eight times a number is the same as three times the value of two times the number -1"

Let x be the number

It can be written as

$3+8\times x=3(2\times x-1)$

$3+8x=3(2x-1)$ ( applying the distributive property )

$3+8x=3(2x)+3(-1)$

$3+8x=6x-3$

subtracting (6x-3) on both sides we get

$3+8x-(6x-3)=6x-3-(6x-3)$

$3+8x-6x+3=6x-3-6x+3$

$6+2x=0$ ( ading the like terms )

$2x=-6$

$x=-\frac{6}{2}$

Therefore x=-3

The number x is -3
