Question

why √3×√3 is 3

can you tell me ​

Answer 1

Answer:

y=3√3+√3

CALCULATIONS

The radical 3√3+√3 can be factored (simplified) to reveal a more compact if not more manageable expression:

y=3√3+√3 (Factor out the common factor “square root 3” and distribute the factor over addition inside of a set of parentheses)

y=√3(3+1)

y=√3(4)

y=

4√3 (decimal: 6.928203 to 6d. p)

According to question:

To prove:

${\huge \sqrt{3} \times \sqrt{3} = 3}$

PROOF:

As we know,√x is the opposite of square of x.

Square of x is the double of x which is ${x}^{2}$ where $\sqrt{x}$ is the half of x.

Therefore, if we multiply $\frac{1}{2} \times \frac{1}{2}$ , we get 1.

Similarly, if we multiply $\sqrt{3} \times \sqrt{3}$ , we will get 3.
