г) 3b : 4a

Answer 2

It seems like you've provided a list of mathematical expressions involving variables a and b. Let's break them down:

1. a*4: This expression represents the product of the variable "a" and the number 4. In other words, it's 4 times the value of "a."

2. b*3: Similarly, this expression represents the product of the variable "b" and the number 3. It's 3 times the value of "b."

3. b3 - a4: This expression subtracts the result of a4 from b3. It's the difference between 3 times "b" and 4 times "a."

4. (b3) / (a4): This expression represents the division of b3 by a4. It's the result of dividing 3 times "b" by 4 times "a."

If you have specific values for the variables "a" and "b," you can substitute those values into these expressions to calculate numerical results. Otherwise, these expressions are given in a general form using variables "a" and "b."
