If x3 = 27, what is the value of x?

ipn [44]

Answer:

The value of x is 3

Step-by-step explanation:

Given:

$x^3 = 27$

To Find:

x = ?

Solution:

We Know that

$a = (a^3)^\frac{1}{3}$

$a = (a)^\frac{3}{3}$

We can write 27 as $3 \times 3 \times 3$ = $3^3$

Taking cube root on both sides

$(x^3)^{\frac{1}{3} }= (3^3)^{\frac{1}{3}}$

$x^{\frac{3}{3}} = 3^{\frac{3}{3}}$

$x^1 = 3^1$

x = 3

The area of a circular garden is 121pi

balandron [24]

Answer:

22 pi ft

Step-by-step explanation:

We can use the area to find the radius

A = pi r^2

121 pi = pi r^2

Divide each side by pi

121 = r^2

Take the square root

sqrt(121) = sqrt(r^2)

11= r

Now we need to find the circumference

C = 2*pi*r

C = 2* pi *11

C = 22 pi ft
