If you want to work with real numbers, there is no answer. the square of any number, whether positive or negative, is a positive number, so x2 cannot be -3.
If you accept complex numbers as a solution, the square root of minus 1 is called i (when squared, both i and -i give -1); the square root of -3 is equal to the square root of 3 times i, the square root of -4 is 2i, etc.
Complex numbers are frequently used in some areas of science (electricity, quantum mechanics, and others); in other areas, it just doesn't make sense to use them. Similarly, for some problems fractional solutions, or negative solutions, may be acceptable, for others, not.
I believe the converse is: if 2x equals 6 then x equals 3 inverse: if x doesn't equal 3 then 2x doesn't equal 6 contrapositive: if 2x doesn't equal 6 then x doesn't equal 3
3+10 = 13
x = 7
It is x*sqrt(x) or x^(3/2)
X = 81 sqrt(X) + 3 = 12 ( subtract 3 from each side ) sqrt(X) = 9 (square both sides ) X = 81 ( the square root of 81 is 9 )
I believe the converse is: if 2x equals 6 then x equals 3 inverse: if x doesn't equal 3 then 2x doesn't equal 6 contrapositive: if 2x doesn't equal 6 then x doesn't equal 3
it equals 3.
7xsquare = 7 x square = 1 x = +1 or -1
x = 9
A square root is taking a number X and determining which two same numbers times each other, or Y*Y equal X. If X equals 9, the square root of it is 3; that is 3 (Y) multiplied by 3 (Y) is 9.

15ft x 62ft equals 930 square feet.
36 x 50 yards equals 1,800 square yards. To convert to square feet, you need to multiply by 9 (since 1 yard equals 3 feet). Therefore, 1,800 square yards is equal to 16,200 square feet.
y equals x plus 4 when y equals 0 then x equals 2i i is the square root of negative 1
15ft X 52ft equals 780 square feet.
1.73205081The question could be restated, what number times itself equals 3. To the 8th decimal, the answer is 1.73205081 x 1.73205081 = 3
x is equal to -36
