What is 64x6+27 written as a sum of cubes?​

Mathematics

Answer:

To transform the given expression to the sum of cubes, calculate first the cube root of the terms. The cube root of the first term, 64x^6 is 4x^2 and that of the second term, 27 is 3.

Thus, the answer to this is (4x^2)^3 + 3^3

How do you divide something like this?
nordsb [41]

Answer:

So \frac{x^2-12x+8}{x-5}=(x-7)+\frac{-27}{x-5}

Step-by-step explanation:

Since we are dividing by a linear factor, I'm going to use synthetic division.

Since the linear factor that we are dividing by is (x-5), I'm going to put 5 on the outside:

5    |     1       -12       8

      |              5      -35

      |--------------------------

           1         -7      -27

So the quotient x-7 while the remainder is -27.

So \frac{x^2-12x+8}{x-5}=(x-7)+\frac{-27}{x-5}

You could do long division if you prefer:

           x-7

         ------------------------

(x-5) |   x^2-12x+8

        - (x^2-5x)

        --------------------------

                -7x+8

              -(-7x+35)

         ---------------------

                     -27

You still get the same thing that the quotient is x-7 and the remainder is -27.

Explain why the steps for solving equations are usually given as removing grouping symbols first, even though it is not necessar
finlep [7]
This is because simplifying the equation before solving it will lead you to the answer at a much faster rate. For example, in the given equation, the long way would be to distribute 2 to (x+3). Then, you transpose them and combine like terms. Until you get to x + 3 = 8. But if you simplify it first, you will see that it is straightforward. It will lead you to the answer right away which is x + 3 = 8. It saves you from the hassle of doing more algebra :)

I don't get what it is asking me to do
Ksju [112]
What you do here is you input 11 in as a value of x:
t=3n-7\\
t=3(11)-7\\
t= 33-7\\\\
t=26
