Simplify nine square root of two minus three square root of seven plus square root of eight minus square root of twenty eight.

avanturin [10]

Answer:

$11\sqrt{2} - 5\sqrt{7}$

Option (A) is the correct answer.

Step-by-step explanation:

$9\sqrt{2} - 3\sqrt{7} + \sqrt{8} - \sqrt{28}$

Now, $\sqrt{8} = \sqrt{2 \times 2 \times 2} = 2\sqrt{2}$

$\sqrt{28} = \sqrt{2 \times 2 \times 7} = 2\sqrt{7}$

∴ $9\sqrt{2} - 3\sqrt{7} + \sqrt{8} - \sqrt{28}$

= $9\sqrt{2} - 3\sqrt{7} + 2\sqrt{2} - 2\sqrt{7}$

= $9\sqrt{2} + 2\sqrt{2} - 3\sqrt{7} - 2\sqrt{7}$

= $11\sqrt{2} - 5\sqrt{7}$

Therefore option (a) is the correct answer.

Schach [20]

Answer:

$\large\boxed{343=7\sqrt7}\\\boxed{10\sqrt{96}=40\sqrt6}$

Step-by-step explanation:

$343=7^3=7^2\cdot7\\\\\sqrt{343}=\sqrt{7^2\cdot7}\qquad\text{use}\ \sqrt{ab}=\sqrt{a}\cdot\sqrt{b}\\\\=\sqrt{7^2}\cdot\sqrt7\qquad\text{use}\ \sqrt{a^2}=a\ \text{for}\ a\geq0\\\\=7\sqrt7\\=====================\\\\96=16\cdot6\\\\10\sqrt{96}=10\sqrt{16\cdot6}=10\sqrt{16}\cdot\sqrt6=(10)(4)\sqrt6=40\sqrt6$
