Question

A) 1,2a(0,2a + b), если a = 0,08, b = -1,92

Answer 1

Ответ:

1,2а(0,2а+b)=0,24a²+1,2ab=0,24•0,08²+1,2•0,08(-1,92)=0,24•0,0064-0,096•1,92=0,001536-1,8432=-1,841664

Answer 2

To evaluate the expression 1,2a(0,2a + b) with the given values of a = 0.08 and b = -1.92, we substitute these values into the expression and perform the calculations.

1,2a(0,2a + b) = 1.2 * 0.08 * (0.2 * 0.08 + (-1.92))

Let's calculate the expression step by step:

0.2 * 0.08 = 0.016 0.016 + (-1.92) = -1.904 1.2 * 0.08 * (-1.904) = -0.022848

Therefore, when a = 0.08 and b = -1.92, the value of the expression 1,2a(0,2a + b) is approximately -0.022848.
