Simplify. ^3√−8x^24y^36

Pachacha [2.7K]

Answer: -2 $x^{8}y^{12}$

Explanation:

We have given that,

∛-8 $x^{24}$ $y^{36}$

Now we will using the formula,

i.e. (√ab=√a×√b)

=∛-8×∛ $x^{24}$ ×∛ $y^{36}$

Here, we use the formula i.e.

$(a^{m})^{1/_n}$ = $a^{m/_n}$

∴ -2× $x^{{24}/_3}$ × $y^{36/3}$

= -2 $x^{8}$ $y^{12}$

A balloon has a circumference of 23 cm. Use the circumference to approximate the surface area of the balloon to the nearest squa

AveGali [126]

To get the surface area of a sphere, we need to have the radius. We are given the circumference. The circumference formula is C=2πr. We need to solve for r.
23 = 2πr
r=3.66

The calculation for surface area is A = 4πr^2.
A = 4π(3.66)^2

Solve for A.

A= 168 cm^2.
