Question

Combine these radicals - square root 5 - 3 square root 5

Answer 1

Answer:

$-4\sqrt{5}$

Step-by-step explanation:

Given expression: (square root 5) - (3 square root 5)

• ⇒ $-\sqrt{5} - 3\sqrt{5}$

Since we have √5 common in both terms, let's factor √5.

• ⇒ $\sqrt{5} - 3\sqrt{5}$
• ⇒ $\sqrt{5} \times (-1 - 3)$

Finally, we can simplify;

• ⇒ $\sqrt{5} \times (-4)$
• ⇒ $-4\sqrt{5}$

Therefore, the combined radical of (square root 5) - (3 square root 5) is $-4\sqrt{5}$

Answer 2

Answer:

-1√5-3√5=(√5)(-1-3)=(√5)(-4)=-4√5

Step-by-step explanation:

if you combine the radicals, you will receive the answer that is shown above.
