Question

(3+0,2)*(3 во 2 степени - 3×0,2+ 0,2 во 2 степени) = ?

Answer 1

(3+0,2)*(9-0.6+0,4)=3,2*8=25,6

Answer 2

Let's first simplify the expression inside the parentheses:

3 во 2 степени = 3 * 3 = 9 3×0,2 = 0,6 0,2 во 2 степени = 0,04

So, the expression inside the parentheses becomes:

9 - 0,6 + 0,04 = 8,44

Now, we can substitute this value back into the original expression:

(3+0,2) * 8,44 = 3,2 * 8,44 = 27,008

Therefore, the value of the expression is 27,008.
