Question

Multiply root 3 (root 7-root 3)

Answer 1

The answer is √21 - 3 or 1.582 (approx)

Given

√3 (√7 - V3)

To find

The product

Solution

√3 (√7 - V3)

Now we will use distributive property i.e

a(b + c) = ab + ac

= √(3X7) - √(3X3)

= √21 - √9

We know that √9 = 3

Since there are no similar pairs of √21, there is no definite square root for the same.

Therefore answer is √21 - 3

However, with the use of calculator, we obtain √21 = 4.582 (approx)

Therefore √21 - 3 = 1.582 (approx)

Hence, the answer is √21 - 3 or 1.582 (approx)
