Question

6,36+а+(-2,9)+(-4,36)+2,9 При а =4,5

Answer 1

6,36+4,5-2,9-4,36+2,9=6,36+4,5-4,36=10,86-4,36=6,5

Answer 2

To solve this expression, we can substitute the value of a with 4.5 and then simplify the expression using the rules of addition and subtraction of real numbers.

So, when a=4.5, we have:

6.36 + 4.5 + (-2.9) + (-4.36) + 2.9

Simplifying the expression by adding and subtracting the given numbers, we get:

= (6.36 - 4.36) + 4.5 + (-2.9 + 2.9) - 4.36

= 2 + 4.5 + 0 - 4.36

= 2.14

Therefore, the value of the expression when a=4.5 is 2.14.
