Question

Вычислитеа) 1/13*(√1.69)-0.1=б) (√5/4)²=​

Answer 1

Ответ:

0

Пошаговое объяснение:1/13*1.3 = 1/10

1/10-0.1 = 0

Answer 2

а)

1/13*(√1.69)-0.1 = (1/13)*√1.69 - 0.1

First, we need to simplify the square root of 1.69:

√1.69 = √(1.69*100/100) = √(169/100) = 13/10

Now we can substitute this value in the original expression:

1/13*(√1.69)-0.1 = (1/13)*(13/10) - 0.1 = 1/10 - 0.1 = -0.9

Therefore, 1/13*(√1.69)-0.1 = -0.9.

б)

(√5/4)² = (√5/4)*(√5/4)

To simplify this expression, we can use the property that (ab)² = a²b²:

(√5/4)² = (√5/4)(√5/4) = (√(55)/4*4) = 5/16

Therefore, (√5/4)² = 5/16.
