when we say 2a this means 2 * a and when we say a2, this means a * 2. so at the end of the day we will get same answers.

## What does a2 b2 mean?

A theorem stating that the square of the length of the hypotenuse (the longest side) of a right triangle is equal to the sum of the squares of the lengths of the other sides. It is mathematically stated as c^{2} = a^{2} + b^{2}, where c is the length of the hypotenuse and a and b the lengths of the other two sides.

## What is formula of A² B²?

The (a^{2} + b^{2}) formula is expressed as a^{2} + b^{2} = (a +b)^{2} -2ab.

## Is 2A equal to a2?

answer in M. 2. The reaction 2A → A2 was experimentally determined to be second order with a rate constant, k, equal to 0.0265 M–1min–1. The reaction 2A → A2 was experimentally determined to be second order with a rate constant, k, equal to 0.0265 M–1min–1.

## Is 2A and A² the same?

2a means that “a” is multiplied by 2 or twice and a^2 means that “a” is multiplied by itself once to become square of itself as “a×a”. The difference between the two is one is the answer of addition and second is the answer of square of a number. And if I multiply, a*a, It is a^2 (base is same, so powers can be added).

## Is a 2 B 2 C 2 only for right triangles?

Pythagorean theorem: If a triangle is a right triangle (has a right angle), then a2+b2=c2. Converse: If a2+b2=c2 in a triangle with c is the longest side, then a triangle is a right triangle. Obtuse: Has a single obtuse (greater than 90 degree) angle and 2 acute angles.

## What is a2 2ab b2?

a2 + 2ab + b2 = (a + b)2. and. a2 – 2ab + b2 = (a – b)2. 2. To use: if the first and last terms of a trinomial are squares, try writing a perfect square; then use the square formula to see if you are correct.

## Is A² B² equal to a B ²?

(A²-B²) = (A-B)² + 2AB.

## What is the product of X A and X B )?

x^{2} + (a – b)x – ab.

## What is A⁴ B⁴?

(d) a⁴ – b⁴ = (a² + b²) (a² – b²) = (a – b) (a³ + a²b + ab² + b³) Special Factors. (a) (a + b + c) (bc + ca + ab) – abc = (b + c) (c + a) (a + b) (b) (a + b + c)³ – a³ – b³ – c³ = 3 (a + b) (b + c) (c + a) (c) a³ + b³ + c³ – 3abc = (a + b + c) (a² + b² + c² – ab – bc – ca) ➢ If a³ + b³ + c³ = 3abc.

## What is A2 equal to?

The A2 size print measures 42.0 x 59.4cm, 16.53 x 23.39 inches, if mounted 59.4 x 76.6cm, 23.39 x 30.16 inches. The A3 size print measures 29.7 x 42.0cm, 11.69 x 16.53 inches, if mounted 40.6 x 50.8cm, 15.98 x 20 inches.

## What is 2a If a 3?

thus, if a=3, then 2a squared = 2×3 times 2×3 = 6 times 6 or 36. This is different from 2a^2, which means 2 times the square of a, or 2xaxa. In this case, 2a^2 would be 2x3x3, or 18.

## What is 3a squared when a =- 3?

If a=-3 then 3a squared will be equal to 27.

## What is equivalent to A /( B C?

(A/B)/C is equal to A/(BC) because you are still dividing a by b and c. For example (20/5)/2 is equal to 2 while 20/(5*2) is also equal to 2. This is because of the order of operations. First you do what is in the parentheses and then do the outside stuff.

## What does 2y mean in math?

2y means 2 times you. That’s like saying 2×3 that is two times 3 so that is 3 +3 . So y+y and 2*y both are correct.

## What does AB mean in math?

Common Symbols Used in Geometry Meaning Example Line “AB” Ray “AB” Congruent (same shape and size) ABC DEF Similar (same shape, different size) DEF MNO.

## How do you find a hypotenuse?

The hypotenuse is termed as the longest side of a right-angled triangle. To find the longest side we use the hypotenuse formula that can be easily driven from the Pythagoras theorem, (Hypotenuse)^{2} = (Base)^{2} + (Altitude)^{2}. Hypotenuse formula = √((base)^{2} + (height)^{2}) (or) c = √(a^{2} + b^{2}).

## Who invented A² B²?

“The quadratic equation — (A+B)2 = A2 + B2 + 2AB — was discovered by Indian saint Dharacharya,” he said.

## How do you explain AB 2?

The (a + b)^{2} formula is the algebraic identity used to find the square of the sum of two numbers. To find the formula of the binomial in the form (a + b)^{2}, we will just multiply (a + b) (a + b).

## What is the value of A² B² ²?

⭐So, (a²+b²)²= a⁴+ 2a²b²+ b².
