Question

√8-(√10-√5)*√5 плииз

Answer 1

=2√2-(√50-5)=2√2-(5√2-5)=2√2-5√2+5=-3√2+5

Answer 2

получиться -0.7574 т.к  √10-√5=0.9262, 0.9262*√5=2.0710, 2.0710-√8=  -0.7574

Answer 3

To simplify the expression √8 - (√10 - √5) * √5, you can follow these steps:

1. Start by simplifying each term under the square root. √8 = √4 * √2 = 2√2 √10 = √5 * √2 √5 remains as it is.

2. Replace these values in the original expression: 2√2 - (2√5 - √5) * √5

3. Now, distribute the terms within the parentheses and simplify: 2√2 - 2√5 * √5 + √5 * √5

4. Multiply the terms with square roots: 2√2 - 2√25 + √25

5. Simplify the square roots: 2√2 - 2√25 + √25 = 2√2 - 2 * 5 + 5

6. Perform the remaining arithmetic: 2√2 - 10 + 5

7. Finally, simplify further: 2√2 - 5

So, √8 - (√10 - √5) * √5 simplifies to 2√2 - 5.
