Question

2ab^2=5 Знайти ab^2, 7ab^2, -4a^2b^4

Answer 1

ab^2=5/2. 7ab^2=3,5*2ab^2=3,5*5=17,5.  -4a^2b^4= -(2ab^2)^2= -(5)^2= -25. в последнем не уверен. скорее всего нет.

Answer 2

To find the values of the expressions, we need more information about the variables involved. As it stands, the equation you provided is 2ab^2 = 5, which only allows us to find the value of ab^2.

Step 1: Solve for ab^2: 2ab^2 = 5

To isolate ab^2, divide both sides by 2: ab^2 = 5/2

Now, we have the value of ab^2, which is 5/2.

Step 2: Calculate 7ab^2: 7ab^2 = 7 * (5/2) = 35/2

The value of 7ab^2 is 35/2.

Step 3: Calculate -4a^2b^4: Since we don't have information about the value of "a," we cannot compute -4a^2b^4 without knowing the value of "a."

Therefore, the results are: ab^2 = 5/2 7ab^2 = 35/2

But we cannot determine -4a^2b^4 without additional information about the variable "a."
