What is the cube root of 27a^l2? -3a4 -3a 3a 3a*

GuDViN [60]

Answer:

$3a^4$

Step-by-step explanation:

What is the cube root of $27a^{12}$ ? This is the question.

We can write:

$\sqrt[3]{27a^{12}}$

We will use the below property to simplify:

$\sqrt[n]{a*b}=\sqrt[n]{a} \sqrt[n]{b}$

So, we have:

$\sqrt[3]{27a^{12}} =\sqrt[3]{27} \sqrt[3]{a^{12}}$

We will now use below property to further simplify:

$\sqrt[n]{x} =x^{\frac{1}{n}}$

Thus, we have:

$\sqrt[3]{27} \sqrt[3]{a^{12}} =3*(a^{12})^{\frac{1}{3}}$

We know power to the power rule: $(a^z)^b=a^{zb}$

Now, we have:

$3*(a^{12})^{\frac{1}{3}}\\=3*a^{\frac{12}{3}}\\=3a^4$

This is the correct answer: $3a^4$

What is the volume of the following triangular pyramid?

Readme [11.4K]

Answer:

The volume of the triangular pyramid

V = 566.66 in³

Step-by-step explanation:

Step(i):-

The volume of the triangular pyramid

$= \frac{1}{3} X base area X height$

Base area = Area of the triangle

$A= \frac{1}{2} X base X height$

Given the base of the triangle (b) = 17in

Given Height of the triangle (h ) =10 in

$A= \frac{1}{2}( 17 ) (10) = 85$

The base area of the pyramid ( A) = 85 in²

Step(ii):-

Given the height of the pyramid (h) = 20in

The volume of the triangular pyramid

$= \frac{1}{3} X base area X height$

The volume of the triangular pyramid

= $= \frac{1}{3}( 85)(20) = 566.66$

Final answer:-

The volume of the triangular pyramid

V = 566.66 in³
