Answer 1

Ответ:

Пошаговое объяснение:

а)1/3ab^4•(-3,6)a^3b= -1/2a^4b^5

б)5 1/2c^2d^5•(-8/33)cd=-1 1\3c³d^6

Answer 2

To simplify the given expressions, let's evaluate them step by step:

a) 1/3ab^4 • (-3.6)a^3b

First, let's multiply the coefficients: 1/3 • (-3.6) = -1.2.

Next, we can multiply the variables with the same base by adding their exponents:

a^1 • a^3 = a^(1 + 3) = a^4 b^4 • b^1 = b^(4 + 1) = b^5

Putting it all together, the expression becomes:

-1.2a^4b^5

b) 5 1/2c^2d^5 • (-8/33)cd

To multiply the coefficients, we need to convert the mixed number to an improper fraction:

5 1/2 = 11/2

Now, let's multiply the coefficients:

11/2 • (-8/33) = -88/66 = -4/3 (simplified)

Next, we can multiply the variables with the same base by adding their exponents:

c^2 • c^1 = c^(2 + 1) = c^3 d^5 • d^1 = d^(5 + 1) = d^6

Finally, we combine all the terms:

-4/3c^3d^6

So, the simplified expressions are: a) -1.2a^4b^5 b) -4/3c^3d^6
