Answer:

Step-by-step explanation:

${(5 - 6)}^{2} \times (4 + 3)$

Calculate the difference

$= {( - 1)}^{2} \times (4 + 3)$

Add the numbers

$= {( - 1)}^{2} \times 7$

Evaluate the power

$= 1 \times 7$

Any expression multiplied by 1 remains the same

$= 7$

Hope this helps...

What is the simplified form of the following expression?

Amanda [17]

You have sqrt(8), sqrt(18), and sqrt(2).
You need to simplify the radicals.
sqrt(2) is already simplified.
For both sqrt(8) and sqrt(18), you need to factor out the greatest perfect square.

8 = 4 * 2
You can take the square root of 4 and put it outside the root.

18 = 9 * 2
You can take the square root of 9 and put it outside the root.

$5 \sqrt{8} - \sqrt{18} -2 \sqrt{2} =$

$= 5 \sqrt{4 \times 2} - \sqrt{9 \times 2} -2 \sqrt{2}$

$= 5 \times 2\sqrt{2} - 3 \sqrt{2} -2 \sqrt{2}$

$= 10\sqrt{2} - 3 \sqrt{2} -2 \sqrt{2}$

$= 5\sqrt{2}$
