Answer 2

Ответ:

a) 5

b) 1/3

d) 76

Пошаговое объяснение:

a) √0,04 * 25

√0,04 = √1/25 = 1/5

получаем

1/5 * 25  = 25/5 = 5

b) √3/√27

поделим дробь на √3,получаем

1/√9 = 1/3

d) 4*√(-19)^2

√(-19)^2 = √19^2 = 19

4 * 19 = 76

Answer 3

a) √0.04 * 25: √0.04 is equal to 0.2, so you have:

0.2 * 25 = 5

b) √(3/√27): First, simplify the expression inside the square root:

√(3/√27) = √(3/√(9 * 3))

Since √(9) = 3, you can further simplify:

√(3/√(9 * 3)) = √(3/√(3 * 3))

Now, √(3/√(3 * 3)) = √(3/3)

Since √(3/3) = √1 = 1, the answer is 1.

c) 4 * √((-19)^2): First, calculate (-19)^2:

(-19)^2 = 361

Now, take the square root of 361:

√361 = 19

Finally, multiply by 4:

4 * 19 = 76
