To convert square feet into square metres, multiply the number by 0.30482. Therefore, 75 square feet is equal to 75 x 0.30482 = 6.967728 square metres.

Yes.

75 = 25 x 325 is a square number: 5² = 25, so ( √75 ) = (√5²)(√3) = 5√3

Only whole numbers are even or odd, and the square root of 75 is not a whole number.

No, it is not a square number. The definition in the world of mathematics is that a number is square if it is the product of an integer being multiplied by itself ("squared") such as 9 is a square as it is the product of 3 x 3. 75 is not a square since its square root is not an integer. The nearest square number would be 81 (9 x 9).

The square root of (any number that isn't a perfect square) is irrational.

Square root of 75 is about 8.660254038 so it is 9

The square roots of -75 are [ +5i sqrt(3) ] and [ -5i sqrt(3) ]. Both of them are irrational and imaginary.

Yes, in so far as all numbers are squares (of some number). But it is not a perfect square.

The square root of 75 is: ± 8.660254

The square root of 75 = 8.660254030.....

No. The square root of most numbers is irrational - only if the number of which you take the root happen to be perfect squares, do you get a rational root. In this case, to take the square root of 3/4, 3 is not a perfect square, so the root is not rational. Or you can take .75 to be 75/100; once again, 75 is not a perfect square, so the root is irrational.

75 square feet is equivalent to 6.97 square meters.

75 (square meters) = 807.293281 square feet.

No, there aren't any square numbers between 70 and 80. From 70 to 80, no number has a perfect square root, so no square number exists between 70 to 80.

The square root of 75 is ~8.66

Square root (75) / square root (3) = 5

75 square meters converts to about 807.3 square feet.
