Help me answer the question j

Answer 1

The value of the expression is 252

Step-by-step explanation:

The expression that we have to evaluate in this problem is

$7x^2y$

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:

$7x^2y=7\cdot (3)^2\cdot (4)$

First, we calculate the square of 3, which is:

$3^2 = 3\cdot 3 = 9$

Substituting into the expression,

$7\cdot 3^2 \cdot 4 = 7\cdot 9 \cdot 4$

Now we multiply everything and we get:

$7\cdot 9 \cdot 4 = 252$
