Question

Twice of square root of a natural number 12. Then what is the twice of that number

Answer 1

Given :- Twice of square root of a natural number 12. Then what is the twice of that number ?

Solution :-

Let us assume that, the number is x .

so,

→ square root of x = 12

→ √(x) = 12

squaring both sides we get,

→ x = (12)²

→ x = 144 .

therefore,

→ Twice of x = 2 * 144 = 288 (Ans.)

SOLUTION

GIVEN

Twice of square root of a natural number 12.

TO DETERMINE

The twice of that number

EVALUATION

Let n be the natural number

Now it is given that twice of square root of a natural number 12

So by the given condition

$\sf{2 \sqrt{n} = 12 }$

$\sf{ \implies \: \sqrt{n} = 6 }$

$\sf{ \implies \:n = 36 }$

So the natural number = 36

Now twice of that number = 2 × 36 = 72

FINAL ANSWER

Hence the required answer = 72
