-1

Пошаговое объяснение:

3*(1/3)^2+1-3*(1/3)*(2+1/3)=3*1/9+1-(2 1/3)=1/3+1-(2 1/3)=-1

Answer 2

To solve the given expression, let's break it down step by step:

First, let's simplify the expression within the parentheses: 2 + 1/3 = 6/3 + 1/3 = 7/3

Now, let's simplify the multiplication and division operations within the expression: 3 * (1/3) = 3/3 = 1

Now, let's substitute the simplified values back into the original expression:

3 * (1/3)^2 + 1 - 3 * (1/3) * (2 + 1/3)

= 3 * (1/3)^2 + 1 - 3 * (1/3) * (7/3)

= 3 * (1/9) + 1 - 3 * (1/3) * (7/3)

= 3/9 + 1 - 3/3 * 7/3

= 1/3 + 1 - 1 * 7/3

= 1/3 + 1 - 7/3

Now, let's find a common denominator for the fractions:

= 1/3 + 3/3 - 7/3

= (1 + 3 - 7)/3

= -3/3

= -1

Therefore, the value of the expression 3*(1/3)^2+1-3*(1/3)*(2+1/3) is -1.
