What is the following quotient? StartFraction 6 minus 3 (RootIndex 3 StartRoot 6 EndRoot) Over RootIndex 3 StartRoot 9 EndRoot E

Bezzdna [24]

Exponent properties help us to simplify the powers of expressions. The quotient of the given expression $\dfrac{6 - 3(\sqrt[3]{6})}{\sqrt[3]{9}}$ is (2∛3 - ∛18).

<h3>What are the basic exponent properties?</h3>

${a^m} \cdot {a^n} = a^{(m+n)}\\\\\dfrac{a^m}{a^n} = a^{(m-n)}\\\\\sqrt[m]{a^n} = a^{\frac{n}{m}}\\\\(a^m)^n = a^{m\times n}\\\\(m\times n)^a = m^a\times n^a\\\\$

Given to us

$\dfrac{6 - 3(\sqrt[3]{6})}{\sqrt[3]{9}}$

We will solve the problem using the basic exponential properties,

$\dfrac{6 - 3(\sqrt[3]{6})}{\sqrt[3]{9}}\\\\ = \dfrac{6}{\sqrt[3]{9}} - \dfrac{3(\sqrt[3]{6})}{\sqrt[3]{9}}\\\\ = (6\cdot 3^{-\frac{2}{3}}) - [3 \cdot (2 \cdot 3)^{-\frac{2}{3}}3^{-\frac{2}{3}}]\\\\= (2 \cdot 3 \cdot 3^{-\frac{2}{3}}) - [3 \cdot 2^{-\frac{2}{3}} \cdot 3^{-\frac{2}{3}}3^{-\frac{2}{3}}]\\\\$

$= [2 \cdot 3^{(1-\frac{2}{3})}] - [2^{\frac{1}{3}}\cdot 3^{(1+\frac{1}{3} - \frac{2}{3})}]\\\\= [2 \cdot 3^{(\frac{1}{3})}] - [2^{\frac{1}{3}}\cdot 3^{(\frac{2}{3})}]\\\\= 2\sqrt[3]{3} - \sqrt[3]{2}\sqrt[3]{9}\\\\=2\sqrt[3]{3} - \sqrt[3]{18}$

Hence, the quotient of the given expression $\dfrac{6 - 3(\sqrt[3]{6})}{\sqrt[3]{9}}$ is (2∛3 - ∛18).

A sports ball has a diameter of 15 cm. Find the volume of the ball and select the correct units. Round your answer to 2 decimal

Setler79 [48]

The volume of the ball has a diameter of 15 centimeters around 2 decimal places is 1767.15 cubic centimeters.

<h3>What is Geometry?</h3>

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

A sports ball has a diameter of 15 cm.

Then the radius of the ball will be

r = d/2

r = 15/2

r = 7.5 cm

Then the volume of the ball will be

$\rm Volume = \dfrac{4}{3} \times \pi \times r^3\\\\Volume = \dfrac{4}{3} \times \pi \times 7.5^3\\\\Volume = \dfrac{4}{3} \times \pi \times 421.875\\\\Volume = 1767.15\ cm^3$

Im losing my sanity over this question please can someone help me lol

algol13

There are 5 sides in this shape.

(5-2)(180) = 540. There is 540 degrees in this shape.

111 + c + (c + 10) + 120 + 91 = 540

111 + 2c + 10 + 120 + 91 = 540

2c = 208

c = 104

answer: 104
