Answer 1

Dude, it is 3.

3×3= 9

Answer 2

Answer:

0.948 ( approx )

Step-by-step explanation:

Here, the given problem,

Square root of 0.9 or √0.9

We can find it by long division method.

Which has the following steps,

Step 1 : Write 0.9 as 0.90000000 then group the digits in pairs ( they are called period ), starting with the 0 at the ones place,  

Step 2: find the largest number whose square is equal to or just less than the first period i.e 90, Take this number as the divisor and also as the quotient.

Step 3: Subtract the product of the divisor and the quotient from the first period and bring down the next period to the right of the remainder. This becomes the new dividend.

Step 4: Then, the new divisor will obtain by taking two times the quotient and annexing with it a suitable digit which will be also taken as the next digit of the quotient, chosen in such a way that the product of the new divisor and this digit will equal to or just less than the new dividend.  

Step 5: Repeat steps (2), (3) and (4) for all periods till they have been finished.

By the above steps,

We get,

√0.9 = 0.948,

Note : we can get much accurate answer by increasing zeroes behind 9.
