0.0625 has a grand total of 2 square roots, and they're both real. They are +0.25 and -0.25
The two square roots of 400 are: 20 and -20.
( +0.063246 ) and ( -0.063246 ).These numbers are rounded.These are the only square roots of 0.004. There are no more real ones,and no imaginary or complex ones.
.06 and .06
Yes, if the number whose square root we are taking is greater than 0. Only if you try to take the square root of a negative number will you get back an imaginary number. Square roots are often irrational, but that's different from real versus imaginary.
It is: 6
There are no real square roots of -256. But using complex numbers the square roots of -256 are 16i and -16i.
0.0625 has a grand total of 2 square roots, and they're both real. They are +0.25 and -0.25
There are two roots, both real: -13 and +13
The square roots of any positive real number are a positive and a negative real number. The square roots of any negative real number are a positive and a negative imaginary number. The square roots of any imaginary number or any complex number are two complex numbers.
The two square roots of 400 are: 20 and -20.
They are called real numbers. Negative square roots must be complex numbers.
Negative numbers have no real square roots.-144 has two square roots: 12i and -12i.
The short answer is "Nothing". In the complex domain, the number of nth roots of any real number is n. Every non-negative real number has 2 square roots. Every real number has 3 cube roots. Every non-negative real number has 2 real square roots and 2 imaginary ones. and so on. So what?
No. Negative numbers are real but their square roots are not.
None. The square of any real number must be non-negative.
The real roots of what, exactly? If you mean a square trinomial, then: If the discriminant is positive, the polynomial has two real roots. If the discriminant is zero, the polynomial has one (double) real root. If the discriminant is negative, the polynomial has two complex roots (and of course no real roots). The discriminant is the term under the square root in the quadratic equation, in other words, b2 - 4ac.
