Question

3a2b-1ab2+2a2b-6ab2+9ab2 если a=0,2

Answer 1

Ответ:

А b чему равно не получится посчитать

Answer 2

To evaluate the expression 3a2b - 1ab2 + 2a2b - 6ab2 + 9ab2 when a = 0.2, we substitute the value of a into the expression and perform the calculations.

Let's start by substituting the value of a = 0.2:

3(0.2)2b - 1(0.2)b2 + 2(0.2)2b - 6(0.2)b2 + 9(0.2)b2

Simplifying this expression further:

= 0.12b - 0.04b2 + 0.08b - 1.2b2 + 1.8b2

Now, we combine like terms:

= (0.12b + 0.08b) + (-0.04b2 - 1.2b2 + 1.8b2)

= 0.20b + 0.56b2

Therefore, when a = 0.2, the expression 3a2b - 1ab2 + 2a2b - 6ab2 + 9ab2 simplifies to 0.20b + 0.56b2.
