## What is AB CD?

Given, a:b::c:d. implies a/b = c/d. ⇒ ad = bc.

## What does AB mean in algebra?

Algebraic Terms 2a means 2 × a ab means a × b a means a × a a means a × a × a means a ÷ b means a × a × b ÷ c Adding a.

## What’s the formula of AB?

The formula is (a-b)³=a³-3a²b+3ab²-b³. You convert it to (a-b)³=a³-3ab(a-b)-b³ for an illustration. You take the drawing of the formula (a+b)³=a³+3a²b+3ab²+b³ from above and replace a by the difference a-b.

## What is the value of a³ B³?

Here, volume is in cubic units. Hence, a³-b³ = (a-b) (a²+ab+b²).

## What is the formula of a2 b2?

Introduction: Pythagorean Theorem The formula is A2 + B2 = C2, this is as simple as one leg of a triangle squared plus another leg of a triangle squared equals the hypotenuse squared.

## What is a3 b3 identity?

So this is the required formula of a3−b3. Note – The formula for (a−b)3 can easily be derived by writing (a−b)3=(a−b)(a−b)2. Then using the algebraic identity that (a−b)2=a2+b2−2ab, we can write (a−b)3=(a−b)(a2+b2−2ab), on simplification of this right hand side will help us getting the value of(a−b)3.

## How do you prove a3 b3?

Prove a3-b3=(a-b)(a2+b2+ab) by activity =>a3+b3+3ab(a+b)=(a+b)2 (a+b) =>a3+b3=(a+b)2 (a+b) – 3ab(a+b) =(a+b) {(a+b)2-3ab} =(a+b)(a2+b2+2ab-3ab) =(a+b)(a2+-ab+b2) verified.

## What is the value of a3 b3?

Hence the value of the given term a3+b3 is 370.

## What is a2 +b2?

a2+b2 : as, (a+b)2 = a2 +b2 + 2ab. so, a2+b2=(a+b)2 – 2ab. hence, proved. dome7w and 3 more users found this answer helpful.

## What is a 2 B 2 called?

It ended up very simple. And it is called the “difference of two squares” (the two squares are a2 and b2). This illustration shows why it works: a2 − b2 is equal to (a+b)(a−b)

## What is the value of a2 b2?

Now, we will calculate the value of a2+b2. The value of a2+b2 is equal to 4 + 4 = 8. So, a2+b2 = 8.

## What is the formula of A² B²?

(A²-B²) = (A-B)² + 2AB.

## Who invented a B 2 formula?

Indian saint Dharacharya

## What is a B whole cube?

The formula for A plus B whole cube is: (A+B)3 = A3+B3+3AB(A+B) Or.

## What is the expansion of a3?

This discussion on The expansion of a3 is ___________. a)3 × ab)a + a + ac)3 × 3 × 3d)a × a × aCorrect answer is option ‘D’.

## What is A plus B?

( a + b ) 2. The square of sum of two terms is equal to the squared plus squared plus times product of and . ( a + b ) 2 = a 2 + b 2 + 2 a b. In mathematics, the plus whole squared algebraic identity is called in three ways.

## What is whole square of AB?

The square of this expression is written as ( a − b ) 2 in mathematical form and it is expanded as a 2 − 2 a b + b 2 mathematically. In mathematics, this algebraic identity is used as a formula and it is called in the following three ways.

## What is the whole cube of A minus B?

Write the formula / expansion for (a – b)3. Substitute 13 for (a – b) and 1197 for (a3 – b3). Simplify. Subtract 1197 from each side….Share this page:
