Answer:
Explanation:
The correct answer is option C: (2+)¹ = 2 - 21 - 2t. 21 = 2 · († + ¹ + ¹ + ¹) = 2 · 4 = 2.
To simplify the expression √2 = 2+, we need to find the value of 2+.
In option C, we can see that (2+)¹ is equal to 2 - 21 - 2t. By substituting this expression into the equation, we get:
√2 = 2 - 21 - 2t
Next, we simplify the equation further by expanding the expression 21 into † + ¹ + ¹ + ¹, which equals 4. Therefore, we have:
√2 = 2 - 4 - 2t
Simplifying this equation, we get:
√2 = -2 - 2t
Finally, we can solve for t by isolating it on one side of the equation:
√2 + 2 = -2t
Dividing both sides by -2, we find:
-√2 - 1 = t
So, the correct simplification is (2+)¹ = 2 - 21 - 2t. 21 = 2 · († + ¹ + ¹ + ¹) = 2 · 4 = 2.
