Question

How do I solve it? I don't know how, I can't remember and I don't have my notes ​

Answer 1

Answer:

2.3

Step-by-step explanation:

First we must get rid of the exponent, which is that little 3 at the top.

To do this, we will do:

(-2) × (-2) × (-2) = -8

Now we have -8 + 3.4, which equals -4.6

Next we will combine the numbers in the denominator, to get -2.

Now, all together, we have -4.6/-2.

Last but not least, we will divide -4.6 by -2, to get 2.3

And that's your answer, hope this helps you :)

Sorry if it doesn't, though.

Answer 2

Answer:

-2

Step-by-step explanation:

    $\frac{(-2)^3+3 (4)}{-8+6}$

 $= \frac{-8 + 12}{-2}$

 $= \frac{4}{-2}$    

 $= -2$
