<em>Answer:</em>

<em>The answer is :  </em><em><u>" 1/8 "</u></em><em> . </em>

<em>Step-by-step explanation:</em>

<em>(6 * 3⁻¹) ⁻³ =  (6 / 3¹) ⁻³ = 2⁻³ = 1 / 2³ = </em><u><em>1/8</em></u><em> ; which is answer </em>

<em> </em>

<em><u>Note that n⁰</u></em><em> = 1 ;  regardless  of what "n" is equal to;  </em>

<em>                          and any value, multiplied by "1", equals that same value. </em>

<em> </em>

<em>so "n⁰ " ; which equals "1" ; is simply "canceled out" . </em>

The answer is 2. Here's why:

First if all, anything to the power of 0 is 1.
So n^0=1.
You need to plug in 3 for m, so then 6(3)^-1.
3^-1=1/3.
6 × 1/3= 6/3=2
2×1=2.

[(2x)^x (2x)^2x]^1/x<br>how do you simplify this?
Monica [59]
Note that [ (2x)^x ]^(1/x) = 2x, and that [ (2x)^(2x) ]^(1/x) = (2x)^2 = 4x^2

Multiplying these 2 results together, we get (2x)(4x^2) = 8x^3 (answer)

Pls help i neeed to get my grade up badly
amm1812

Step-by-step explanation:

12 - 1/2r = ( 13 - 3/2r ) - ( 1 - r )

r - 13/6 = ( 7r - 3/2 ) - ( 2/3 + 6r )

13r + 20 = ( 6r + 7 ) + ( 13 + 7r )

-12 + r = ( -8 - r ) + ( 2r - 4 )

mr.lumen replaced a square window with a rectangular one.The new window is 3 ft wider and 2 ft higher than the square one.it has
stira [4]

Alright, lets get started.

Suppose the original square window has the side = x feet

The new window is 3 ft wider and 2 ft higher than the square one.

Means length of the new window will be = (x+3)

Width of the new window will be = (x+2)

So the area of the new window will be = (x+3)(x+2)

So the area of the new window will be = x^2 + 2x + 3x + 6

So the area of the new window will be = x^2 + 5x + 6

As given in question the area of 30 square feet for the new window, hence

x^2 + 5x + 6 = 30

x^2 + 5x - 24 = 0

Factoring

(x+8)(x-3) = 0

x = -8 or x = 3

Side could not be negative hence

side of the original square window will be = 3 feet : Answer

Hope it will help :)

What are the real and complex solutions of the polynomial equation? x^3-64=0
Marrrta [24]

Answer:

Step-by-step explanation:

A difference of two perfect cubes,  x^3 - y^3 can be factored into

(x-y) • (x^2 +xy +y^2) =0  equation 1

x ^3 - 64 = 0

(x)^3 - (4)^3 = 0   equation 2

Now substituting equation 2 into equation 1, we get

(x-4) (x^2+(x).(4) +(4)^2) = 0

(x-4) (x^2+4x+16) = 0

so the solutions are

1) x - 4 =0

x=4

x^2 + 4x + 16 = 0

By using the quadratic formula we get the followig solutions:

          - B  ±  √ B2-4AC

 x =   ————————

                     2A

x =(-4-√-48)/2=-2-2i√ 3 = -2.0000-3.4641i

x =(-4+√-48)/2=-2+2i√ 3 = -2.0000+3.4641i
