Question

6²+7²+8²= ((0,79+2,15)-1,38=​

Answer 1

1)=36+49+64= 149

2)=2,94-1,38= 1,56

Answer 2

Let's break down the calculation step by step:

1. Calculate 6² (6 squared): 6² = 6 * 6 = 36

2. Calculate 7² (7 squared): 7² = 7 * 7 = 49

3. Calculate 8² (8 squared): 8² = 8 * 8 = 64

Now, let's perform the subtraction:

4. Calculate (0.79 + 2.15): 0.79 + 2.15 = 2.94

5. Subtract 1.38 from the result of step 4: 2.94 - 1.38 = 1.56

So, the final result is: 6² + 7² + 8² = 36 + 49 + 64 = 149

And ((0.79 + 2.15) - 1.38) = 1.56

These are two separate calculations, and they are not related to each other.
