Question

For positive real numbers 'a' and 'b' √ab is equal to
√a-b , √a√b ,√a+√b​

Answer 1

Answer:

Step-by-step explanation:

The statement a is greater than or equal to b, denoted by a ≥ b, means a>b or a = b. A real number a is said to be positive if a > 0. The set of all positive real numbers is denoted by R+, and the set of all positive integers by Z+. A real number a is said to be negative if a < 0.

Answer 2

Answer:

For positive real numbers 'a' and 'b' √ab is equal to √a√b.

Explanation:

• Squares and square roots each principles are contrary in nature to every other.
• Squares are the numbers, generated after multiplying a price with the aid of using itself.
• Whereas square root of more than a few is price which on getting accelerated with the aid of using itself offers the authentic price. Hence, each are vice-versa methods.
• For example, the square of two is four and the square root of four is 2.

If n is more than a few then its square is represented with the aid of using n raised to the energy 2, i.e., n2 and its square root is expressed as ‘√n’,

• where ‘√’ is known as radical.

The price below the basis image is stated to be radicand. you could suppose of each fantastic root as having a negative, evil twin.

Properties of square root:

$\sqrt{a} \sqrt{b} = \sqrt{ab} \\ \sqrt[2]{a} = a \\ \sqrt{ {a}^{2} } = a$

hence , by the property:

For positive real numbers 'a' and 'b' √ab is equal to √a√b.
