Math Problem Statement

Fully simplify.

left parenthesis, square root of, minus, 2, end square root, right parenthesis, left parenthesis, square root of, minus, 24, end square root, right parenthesis

(−2​)(−24​)

Solution

You have the expression:

(2)(24)\left(\sqrt{-2}\right) \left(\sqrt{-24}\right)

Let's simplify this step-by-step.

Step 1: Break down the square roots

Both square roots involve negative numbers, so we will work with complex numbers since 1=i\sqrt{-1} = i.

2=2i\sqrt{-2} = \sqrt{2} \cdot i 24=24i=46i=26i\sqrt{-24} = \sqrt{24} \cdot i = \sqrt{4 \cdot 6} \cdot i = 2\sqrt{6} \cdot i

Step 2: Multiply the expressions

Now we multiply the two expressions:

(2i)(26i)\left(\sqrt{2} \cdot i\right) \cdot \left(2\sqrt{6} \cdot i\right)

We first multiply the real parts and then the imaginary parts:

  • Real part: 226=212=223=43\sqrt{2} \cdot 2\sqrt{6} = 2\sqrt{12} = 2 \cdot 2\sqrt{3} = 4\sqrt{3}
  • Imaginary part: ii=i2=1i \cdot i = i^2 = -1

Thus, the result is:

43(1)=434\sqrt{3} \cdot (-1) = -4\sqrt{3}

Final Simplified Expression:

43-4\sqrt{3}
