Answer:  The required cube root of the given expression is 4x^4.

Step-by-step explanation:  We are given to find the cube root of the following expression :

E=64x^{12}~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~``(i)

We will be using the following property :

\sqrt[n]{a}=a^\frac{1}{n}.

Taking cube root on both sides of equation (i), we get

\sqrt[3]E\\\\=\sqrt[3]{64x^{12}}\\\\=(64x^{12})^\frac{1}{3}\\\\=(4^3x^{12})^\frac{1}{3}\\\\=4^{3\times\frac{1}{3}}x^{12\times\frac{1}{3}}}\\\\=4x^4.

Thus, the required cube root of the given expression is 4x^4.

Hello from MrBillDoesMath!

Answer:

2(x+8) = 40


Discussion:

Rewrite the original Question as

" Twice the (sum of a number and 8) is 40"   =>

2                ( x                              +    8 ) = 40 =>

2 (x+8) = 40


which is the third bullet point from the top


Thank you,

MrB

Solve for X and y PLEASE GIVE FULL EXPLANATION HOW YOU GOT IT
Dennis_Churaev [7]

Answer:

(1, -1)

Step-by-step explanation:

we isolate y in the first equation

2x+y=1

-2x.  -2x

y=1-2x

and now we fill y into second equation

4x-2(1-2x)=6

4x-2+4x=6

8x-2=6

   +2 +2

8x=8

/8 /8

x=1

and now to find y we insert x

2(1)+y=1

2+y=1

-2.   -2

y= -1

hopes this helps
