12+root of 35 divided by 2 + 12-2 root of 35 divided by 2

nadya68 [22]

So : $12+ \frac{\sqrt{35}}{2} + \frac{12-2 \sqrt{35} }{2}$ ?

First, you want to bring everything together on the top of the fraction.
12=24/2 so you can have $\frac{24+ \sqrt{35}+12-2 \sqrt{35} }{2}$

Add like terms -- 12 +24 = 36 $\sqrt{35}-2 \sqrt{35} = \sqrt{35}$

Now we are at $\frac{24+ \sqrt{35} }{2}$ Which is the lowest possible simplified version while remaining at exact value.

Feel free to check my math! I kinda did this off the top of my head.

Cuanto es la respuesta de -126=14k?

N76 [4]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \text{k = - 9}}}}}$

Step-by-step explanation:

$\star{ \text{ - 126 = 14k}}$

$\text{step \: 1 \: : Intercambia los lados de la ecuación}$

$\hookrightarrow{ \sf{14k = - 126}}$

$\text{step \: 2 : Divide ambos lados por 14}$

$\hookrightarrow{ \sf{ \frac{14k}{14} = \frac{ - 126}{14}}}$

$\text{step \: 3 \: : Calcular}$

$\hookrightarrow{ \sf{k = - 9}}$

$\text{el valor de k es - 9}$

------------------------------------------------------------

Translation in English:

Step 1 : Swap the sides of the equation

Step 2 : Divide both sides by 14

Step 3 : Calculate

Write an expression with a negative exponent that has a value between 0 and 1/2

aliya0001 [1]

<span>Exponent is a number used to express shorter equation; it is a number that says how many times you are going to multiply the base number.
</span><span>
Exponents have several laws, here are some:
=> x^1 = x
=> x^0 = 1
=> x^-1 = 1/x
=> x^m x^n = X^m+n
=> x^m/x^n = x^m-n

And since we were asked to write an expression with a negative exponent that has a value between 0 and ½
=> 2^ -2 = ½
