15) Evaluate the following expression for x=0.2 and y=3.4: x(y2 - 4)

x(y² - 4) = 1.512

Step-by-step explanation:

We need to evaluate the following expression for x = 0.2 and y = 3.4 :

x(y² - 4)

Put the values of x and y.

x(y² - 4) = (0.2)((3.4)² - 4)

= (0.2)((3.4)² - 4)

= 0.2×7.56

= 1.512

So, the value of the above expression is 1.512

all but the second one
