"Still" implies that the original number is a square number. In that case, the answer is as follows:

There is no number such that it is a perfect sqiuare and that the number increased (or decreased) by 10 is also a perfect square.

And if you do not limit it to perfect square then every non-negative number is a square with the number that is 10 more also being a square.

u can have 81,121,49,9,25,169 ..... if u multiply any odd number by itself it's going to give an odd number and still be a square

Sure. Let's take an example with numbers instead of variables. 8/9 is a rational number - the ratio of two integers. If you square it, you get (8/9)2 = 82/92 = 64/81; that is, if you square each integer, you get an integer again. Therefore, the resulting number is rational again - a number that can be expressed as the ratio of two integers. Replace with any other integers; you will still have a ratio of integers if you square it.

9 square feet is a square yard.90 square feet is 10 square yards.10 square yards at 11 per square yard is 110 just for the tiles.Unless the tiles perfectly fit the area to be covered, you will need to purchase extra tiles since a number of tiles will have to be cut to fit against the wall.For a bathroom you still need to add the cost of tile adhesive, grout, and labor :)

It is still a rational number.

The square root of -121 is imaginary. It has value of i11.It is not rational, irrational, nor real. The coefficient of i, 11, is real and rational, but the result of multiplying i by 11 is imaginary.Now, The Coefficient of (i11) is a complex number, because when dealing with i, the true form is the square root of -1, and so this also means that you still have 2 answers, positive and negative i11, and so the square root of -121 is imaginary, or complex rational number. But, because it is complex, it is not truly rational, all this means is that you end up with aninteger in your complex answer. So, To answer your question, the answer is non of the above, just imaginary. and the value is plus or minus (i11).

Many people still do. But the number has gradually decreased over the last 500 years or so.

Yes. A surd is any irrational number that can be expressed as the root of another number. As pi is a number, although it is a transcendental and hence irrational, the square root of pi is still an irrational number that can be expressed as the square root of another number.

There is no known number that can be squared and produce a negative number since if the number is positive, the result will be positive, and if it's negative the result will still be positive. Accordingly the square roots of negative numbers are normally expressed as a factor of "i" where i is the square root of -1. In that case the square root of -25 is 5i.

The closest square number will be as close to 9999 as you like. For example, 99.999 square = 9999.800001 (0.800001 away) 99.995 square = 9999.000025 (0.000025 away) You could get closer still. The nearest PERFECT square, however, is 10,000.
