The value of the expression is 252
Step-by-step explanation:
The expression that we have to evaluate in this problem is
[tex]7x^2y[/tex]
And we have toe valuate it for
x = 3
y = 4
In order to evaluate the expression, let's substitute the values of x and y into it:
[tex]7x^2y=7\cdot (3)^2\cdot (4)[/tex]
First, we calculate the square of 3, which is:
[tex]3^2 = 3\cdot 3 = 9[/tex]
Substituting into the expression,
[tex]7\cdot 3^2 \cdot 4 = 7\cdot 9 \cdot 4[/tex]
Now we multiply everything and we get:
[tex]7\cdot 9 \cdot 4 = 252[/tex]
