<em>Note: Your exponential expression seems a little unclear. Because 27 is not an exponential expression.</em>

<em>But, I am assuming that your exponential expression is: </em>

  • \:27^{\frac{1}{3}}

<em>The reason is that my solution would still clear your concept about this topic, no matter what the question is. </em>

<em> </em>

Answer:

The simplified value of the exponential expression is:

27^{\frac{1}{3}}=3

Step-by-step explanation:

Assuming the exponential expression

\:27^{\frac{1}{3}}

\mathrm{Factor\:the\:number:\:}\:27=3^3

=\left(3^3\right)^{\frac{1}{3}}

\mathrm{Apply\:exponent\:rule}:\quad \left(a^b\right)^c=a^{bc},\:\quad \:a\ge 0

\left(3^3\right)^{\frac{1}{3}}=3^{3\cdot \frac{1}{3}}

=3^{3\cdot \frac{1}{3}}

=3^1

\mathrm{Apply\:exponent\:rule}:\quad \:a^1=a

=3

Therefore, the simplified value of the exponential expression is:

27^{\frac{1}{3}}=3

A certain circle can be represented by the following equation. x^2+y^2+18x+14y+105=0 What is the center of the circle? What is t
Gre4nikov [31]

Answer:

See below.

Step-by-step explanation:

Recall the equation for a circle:

(x-h)^2+(y-k)^2=r^2, where (h,k) is the center and r is the radius.

We need to turn the given equation into the above format. We do this by completing the square.

First, group them:

(x^2+18x)+(y^2+14y)=-105

For the first section, complete the square for x^2+18x:

x^2+18x+81-81

(x+9)^2-81

Do the same for the second:

y^2+14y

y^2+14y+49-49

(y+7)^2-49

All together:

((x+9)^2-81)+((y+7)^2-49)=-105

(x+9)^2+(y+7)^2-130=-105

(x+9)^2+(y+7)^2=25

The center is (-9,-7).

The radius is \sqrt{25}=5

Anna71 [15]
25% of $160

= (25/100) * 160

= 0.25 * 160

= 40

$40 paid.

Balance owed = $160 - $40 = $120

Balance owed = $120
