Question

(1,4 + 6,2) • (8,76 - 4,9) *

Answer 1

(1,4+6,2)•(8,76-4,9)=29,336 вот

Answer 2

It seems like you're trying to perform some mathematical operations involving vectors. The expression you've provided involves addition, subtraction, and multiplication of vectors. However, there is a missing element in the expression, which is likely the vector you're trying to multiply with. Assuming you have a vector to multiply with, I'll break down the operations step by step.

Let's break down the expression:

1. Addition: (1,4 + 6,2) = (7, 6.2)
2. Subtraction: (8.76 - 4.9) = 3.86

Now, since we're missing the second vector that you want to multiply by, I'll use a placeholder vector (a, b) for the explanation:

3. Multiplication: (7, 6.2) • (a, b) = 7a + 6.2b

So, the simplified expression would be: Expression = (7a + 6.2b) * 3.86

If you have specific values for the second vector (a, b), you can substitute them into the expression to get the final result.
