1 acre is approximately 208.71 feet × 208.71 feet (a square) 4,840 square yards or 43,560 square feet
Writing a number in standard form simply means to express the number in its 'normal' form. Therefore, your example is written in standard form.
210
Well, darling, a 15x14 room would be 210 square feet. To convert that to square yards, you divide by 9 since there are 9 square feet in a square yard. So, the answer is 23.33 square yards. But who's counting anyway?
210 = 2*105 = 2*3*35 = 2*3*5*7. To simplify sqrt(210) you need a pair of factors to form a square. You can then take out the square root, which will be a whole number. Since 210 has no pair of factors, sqrt(210) cannot be simplified.

It is 210.
14.5
14.5
15*2940 = 44100 and the square root of this is 210
That doesn't factor neatly. Applying the quadratic equation, we find two imaginary solutions: 5 plus or minus i times the square root of -185x = 5 + 13.60147ix = 5 - 13.60147iwhere i is the square root of -1
210 is neither a prime number or a square number.
There are infinitely many possible answers. One such is 50*4.2
210 square miles.
In decimal form, 210% is 2.1.
