-4X^4 - 44x^2 + 3600 = 0

divide through by -4:-

x^4 + 11x^2 - 900 = 0

900 = 36 * - 25    and 11 = 36-25  so the factors are

(x^2 + 36)(x^2 - 25)  = 0

x^2 = - 36  giving  x = 6i and -6i

x^2 = 25  giving x = 5 and x = -5

solution set is {-5, 5,  6i, -6i}

Express the radical using the imaginary unit, i
Kipish [7]

Answer:

7i.

Step-by-step explanation:

Note : The given expression must be \sqrt{-49}.

We have to write this radical value in the imaginary value.

The given value can be rewritten as

\sqrt{-49}=\sqrt{49\times (-1)}

\sqrt{-49}=\sqrt{49}\times \sqrt{-1}    [\because \sqrt{ab}=\sqrt{a}\sqrt{b}]

\sqrt{-49}=7\times i    [\because \sqrt{-1}=i]

\sqrt{-49}=7i

Therefore, the required expression is 7i.
