Question

3,7 n - 2,8 n + 4,9 n - n Если n - 0,01

Answer 1

Я сразу упростил
4,8n
при n = -0.01
то 
4,8*(-0,01)=-0,048

Answer 2

To evaluate this expression when n = 0.01, we simply substitute n = 0.01 into the expression and simplify:

3.7n - 2.8n + 4.9n - n = 3.7(0.01) - 2.8(0.01) + 4.9(0.01) - 0.01 (substitute n = 0.01) = 0.037 - 0.028 + 0.049 - 0.01 (multiply) = 0.048 (add and simplify)

Therefore, when n = 0.01, the expression 3.7n - 2.8n + 4.9n - n evaluates to 0.048.
