### What is the formula for a3 b3?

a3 + b3 = (a + b) (a2 – ab + b2 ).

### What is the formula of Acube?

So for a cube, the formulas for volume and surface area are V=s3 V = s 3 and S=6s2 S = 6 s 2 .

### What is a 3 plus B 3?

a3 + b3 formula is read as a cube plus b cube. It is called the sum of cubes (of two numbers) formula. Its expansion is expressed as a3 + b3 = (a + b) (a2 – ab + b2)

### How do you prove a3 b3?

a3 – b3 = (a – b)(a2 + ab + b2) Solution: The algebraic identity a3 – b3 = (a – b)(a2 + ab + b2) is the two cubes‘ identity. This can be proved by considering right hand side term.

### How do you solve AB 3?

How To Use the (a + b)3 Formula Give Steps?

1. Firstly observe the pattern of the numbers whether the numbers have whole ^3 as power or not.
2. Write down the formula of (a + b)3
3. (a + b)3 = a3 + 3a2b + 3ab2 + b3
4. Substitute the values of a and b in the (a + b)3 formula and simplify.

### What is LSA of cuboid?

=2h(l + b) LSA of Cuboid = 2h(l +b) Example: If the length, breadth and height of a cuboid are 5 cm, 3 cm and 4 cm, then find its lateral surface area. Given, Length = 5 cm, Breadth = 3 cm and Height = 4 cm. LSA = 2h(l+b)

### What is the identity of a 2 B 2?

The standard algebraic identities are: a2 – b2 = (a + b)(a – b) (x + a)(x + b) = x2 + (a + b) x + ab. (a + b + c)2 = a2 + b2 + c2 + 2ab + 2bc + 2ca.

### What is the expansion of a3?

3 × a. a + a + a. 3 × 3 × 3.

### How do I expand my ABN?

If a and b are real numbers and n is a positive integer, then (a + b)n =nC0 an + nC1 an – 1 b1 + nC2 an – 2 b2 + … 1. The total number of terms in the binomial expansion of (a + b)n is n + 1, i.e. one more than the exponent n.

### What is the value of (A3 – B3)?

• Answer: (a 3 – b 3) = (a – b) (a 2 + b 2 + ab) Let us prove this by considering a = 4 and b= 2 then (4 3 – 2 3) = (4 – 2) (4 2 + 2 2 + 4 × 2)

### What is the formula for a^3+b^3?

• Basically a^3b^3 has many formulae which are also called as identities. 2)a^3+b^3= (a+b)^3-3ab (a+b). Basically a^3b^3 has many formulae which are also called as identities. 2)a^3+b^3= (a+b)^3-3ab (a+b).

### What is the expanded form of (a^3-B^3)?

• Maths keeps one mentally active. The expanded form of (a^3b^3) is (ab) (a^2+ab+b^2). The expanded form of (a^3+b^3) is (a+b) (a^2-ab+b^2). Early symptoms of spinal muscular atrophy may surprise you. Signs of spinal muscular atrophy can be easily ignored.

### How do you find the value of (a+B)³?

• …You take the drawing of the formula (a+b)³=a³+3a²b+3ab²+b³ from above and replace a by the difference a-b. Then the edges are (a-b)+b with different combinations (on the left). The term (a-b)³ is illustrated by the blue cube (on the right).
