Question

2⁻*2⁻+49 вычислить

Answer 1

$2 - \frac{6}{5} \times 2 - \frac{4}{5} + 49 \frac{1}{2} = 2 - \frac{12}{5} - \frac{4}{5} + 49 \frac{1}{2} = - \frac{6}{5} + 49 \frac{1}{2} = 48.3$

Answer 2

1) 2^(-6/5) * 2^(-4/5) = 2^(-6/5-4/5 ) =2^ (-10/5) =2^(-2) =1/4

2) 49^ 1/2 = √49 =7

3) 1/4 +7 =7 1/4 =7,25

Answer 3

It seems there might be a typo or missing information in the expression you provided. Let me try to interpret what you meant:

If the expression is: 2^(-2) + 49

Here's how you can compute it step-by-step:

1. 2^(-2) means 2 raised to the power of -2, which is equal to 1 / (2^2) = 1 / 4 = 0.25
2. Now, add 49 to the result: 0.25 + 49 = 49.25

So, the answer is 49.25.

If the expression is different from what I assumed, please provide the correct expression so that I can help you compute it.
