Question

1) а² b³+3a² b³ -1,72 a² b³ -5,7a²b³ 2) 1/2 a³c⁷ +1/2 a³c⁷ +1/2 a³c⁷+3/2 a³c⁷

Answer 1

Answer 2

1. The expression you provided is:

a²b³ + 3a²b³ - 1.72a²b³ - 5.7a²b³

To simplify this expression, we can combine like terms. In this case, all the terms have the same base (a²b³), so we can add their coefficients:

1 + 3 - 1.72 - 5.7 = -2.72

Therefore, the simplified expression is:

-2.72a²b³

2. The expression you provided is:

1/2a³c⁷ + 1/2a³c⁷ + 1/2a³c⁷ + 3/2a³c⁷

To simplify this expression, we can combine like terms. Again, all the terms have the same base (a³c⁷), so we can add their coefficients:

1/2 + 1/2 + 1/2 + 3/2 = 6/2 = 3

Therefore, the simplified expression is:

3a³c⁷
