evaluate square root 9/16, if possible?

Answer 1

√ (9/16) = √ 9 / √16 = 3 / 4

Answer 2

answer is +3/4.
because you ask the square root of 9/16.
if you ask, x^2 = 9/16
then the answer should be ± 3/4.
that EQUATION means which number of square provide 9/16.
this is different from to ask what is the square ROOT of 9/16.
so, square root of 9/16 has only one positive number that is + 3/4.

Answer 3

3/4

Answer 4

3/4

Answer 5

√(9/16) = ± 3/4

Never forget to check if the negative square root can apply!

Answer 6

3/4

Answer 7

Your assumption, "if 2+i is a root, then 2-i is likewise a root," is optimal assuming that the polynomial equation has actual huge form coefficients, which it in all risk does given the class which you're in. while you're seeking to ingredient this polynomial, then you definately can do synthetic branch with one root and then with the numerous root. even whether, this might get nasty with complicated arithmetic, which you will or purely isn't attentive to. yet in a distinctive thank you to deal with that's to divide via technique of the "minimum polynomial" of 2+i and a pair of-i. exceptionally, those adult males fulfill the polynomial: [x-(2+i)][x-(2-i)] = x^2 - 4x + 5 This polynomial has to divide the unique polynomial. in many cases, if a+bi is a root of a polynomial with actual coefficients, then a-bi is, too, and the polynomial is divisible via technique of: [x-(a+bi)][x-(a-bi)] = x^2 - 2ax + a^2 + b^2

Answer 8

you will have to simplify it if you want to find the square root of it than you should use a calculator
