When a=2b+6, =(2b+6)3-8b3-36 (2b+6)b-216 =8b3+217+36 (6+b)-8b4-72b2-216b-216 =216+36b-72b2-216b =216-180b-72b2 Now, a=2b+6 b=6-a/2 b=6-(2b+6)/2 2b=5-2b+6 b=3 Therefore, =216-180×3-72×3×3 =-972

Altitude of equilateral triangle = h cm
Let the side of triangle = x cm
As we all know the altitude bisects the side of triangle .

A.T.Q

Area of angled triangle ADC,

area = 1/2 × base × height
= 1/2 × x/2 ×h
= 2xh/2
= xh cm²

Area of triangle ABC = 2 × area of triangle ADC

= 2xh cm²

1. First, we draw a line OA of length 1

2. Now, we draw a perpendicular of length 1 on point A as AB

3. From, Pythagoras Theorem, OB = √2

4. Now, take an arc of length OB, and draw it on the number line which meets as E.

So, at E, we can represent √2 as shown in the figure.

Whole numbers are positive numbers, including zero, without any decimal or fractional parts. They are numbers that represent whole things without pieces. The set of whole numbers is represented mathematically by the set: {0, 1, 2, 3, 4, 5...}.

Given, {tex}2 ^ { \frac { 2 } { 3 } } \cdot 2 ^ { \frac { 1 } { 3 } }{/tex}

We know that  {tex}a ^ { m } \cdot a ^ { n } = a ^ { ( m +n) }{/tex}.

So, {tex}2 ^ { \frac { 2 } { 3 } } \cdot 2 ^ { \frac { 1 } { 3 } } = ( 2 ) ^ { \frac { 2 } { 3 } + \frac { 1 } { 3 } }{/tex}

{tex}= ( 2 ) ^ { \frac { 2+1} { 3} }\\ = ( 2 ) ^ { \frac { 3 } { 3 } }\\=(2)^1\\=2{/tex}

Therefore, the value of  {tex}2 ^ { \frac { 2 } { 3 } } \cdot 2 ^ { \frac { 1 } { 3 } }{/tex} will be  {tex}2{/tex}.

The Golden ratio is a special number found by dividing a line into two parts so that the longer part divided by the smaller part is also equal to the whole length divided by the longer part. It is often symbolized using phi, after the 21st letter of the Greek alphabet.
