What are the elements in rational numbers having multiplicative inverse?
All rational numbers, with the exception of zero (0), have a multiplicative inverse. In fact, all real numbers (again, except for zero) have multiplicative inverses, though the inverses of irrational numbers are themselves irrational. Even imaginary numbers have multiplicative inverses (the multiplicative inverse of 5i is -0.2i - as you can see the inverse itself is also imaginary). Even complex numbers (the sum of an imaginary number and a real number) have multiplicative inverses (the inverse of [5i + 2] is [-5i/29 + 2/29] - similar to irrational and imaginary numbers, the inverse of a complex number is itself complex). The onlynumber, in any set of numbers, that does not have a multiplicative inverse is zero.
Is the square root of 75 a rational number?
The square roots of -75 are [ +5i sqrt(3) ] and [ -5i sqrt(3) ]. Both of them are irrational and imaginary.
What is the conjugate of the complex number 9 plus 5i?
9-5i

Complex ; 9 - 5i It conjugate is ' 9 + 5i'.
How do you factor 9x squared plus 25?
9x2 + 25 has no rational factors. Its factorisation in the complex domain is:(3x + 5i)*(3x - 5i) where i is the imaginary square root of -1.
What is the complex conjugate of the following complex number 7 plus 5i?
The conjugate is 7-5i
Is the square root of 25 irrational?
The sqrt of 25 = 5 which can be written as a recurring decimal. Therefore no, it is not irrational, it is rational.
What is the standard form of negative square root of 5i?
The standard form of a complex number is a+bi. So the standard form of the negative square root of 5i is 0-√(5i).
What is the reciprocal of 3 plus 5i?
1/(3+5i)=(3-5i)/((3+5i)(3-5i))=(3-5i)/(9+25)=(3-5i)/34
Is the square root of negative 25 a rational number?
The square root of -25 is not a real number, as it involves taking the square root of a negative number which results in an imaginary number. In this case, the square root of -25 is 5i, where i represents the imaginary unit. Since rational numbers are a subset of real numbers, the square root of -25, being an imaginary number, is not a rational number.
What do you call the number that multiplies the variable i?
In the number: 5i, 5 is called the coefficient of i.
Complex conjugate of 5i?
0 + 5i Its complex conjugate is 0 - 5i
What is true about the complex number -5-5i?
That 5 is a factor.
