Question

470. 1) 3+√4; 2) 7-√√25; 3)√16-9; ​

Answer 1

Ответ:

1)5

2)2

3)-5

Объяснение:

1)3+2=5

2)7-5=2

3)4-9=-5

Answer 2

Let's calculate each of these expressions step by step:

1. 3 + √4: √4 = 2 So, 3 + √4 = 3 + 2 = 5

2. 7 - √√25: √√25 = √5 (because √25 = 5) So, 7 - √√25 = 7 - √5 (approximately 2.236)

3. √16 - 9: √16 = 4 So, √16 - 9 = 4 - 9 = -5

So, the results are:

1. 5
2. 7 - √5 (approximately 2.236)
3. -5
