Question

√5(√5-√20) упростить выражение, объясните решение.

Answer 1

=корень числа 25 - корень числа 100= 5- 10 = - 5

Answer 2

√5(√5-√20)= √5*√5-√5*√20= 5-√5*2√5=5-2*5=5-10=-5

Answer 3

I can help you with math problems, among other things. To simplify the expression $$\sqrt{5}(\sqrt{5}-\sqrt{20})$$, you can use the following steps:

- Apply the distributive property to get $$\sqrt{5}\cdot\sqrt{5}-\sqrt{5}\cdot\sqrt{20}$$ - Use the property that $$\sqrt{a}\cdot\sqrt{b}=\sqrt{ab}$$ to get $$\sqrt{25}-\sqrt{100}$$ - Simplify the square roots to get $$5-10$$ - Subtract to get the final answer of $$-5$$

Therefore, the simplified expression is $$-5$$. I hope this helps.Ответь+подробно.+√5(√5-√20)+упростить+выражение,+объясните+решение.
