Question

(1/3)‐¹-(-6/7)⁰+(1/2)²:2

Answer 1

Ответ: 2 1/8

Решение:

(1/3)^-1 - (-6/7)^0 + (1/2)^2 : 2 = 3 - 1 + 1/8 = 2 + 1/8 = 2 1/8

Answer 2

Let's break down the expression step by step:

1. (1/3)⁻¹ = 3: This is the reciprocal of 1/3.
2. (-6/7)⁰ = 1: Any number raised to the power of 0 is 1.
3. (1/2)² = 1/4: This is the square of 1/2.

So the expression becomes:

3 - 1 + 1/4

Now, let's add the values together:

3 - 1 + 1/4 = 2 + 1/4 = 8/4 + 1/4 = 9/4

Therefore, the simplified value of the expression is 9/4.
