What is the value of the expression 2x^2y / 4xy when x = 2 and y = 1?
a) 1
b) 2
c) 4
d) 3
b
i meant a not b sorry about that
putting a few parenthesis in for clarification...
2x^(2y)/(4xy)
does = 1 for x=2 and y=1
So, you are correct!
thanks qudditch
To find the value of the expression 2x^2y / 4xy when x = 2 and y = 1, you can substitute the given values of x and y into the expression.
First, substitute x = 2 and y = 1 into the expression:
2(2)^2(1) / 4(2)(1)
Next, simplify the expression:
2(4)(1) / 8
Now, do the calculations:
8 / 8 = 1
Therefore, the value of the expression is 1.
So, the correct answer is option a) 1.
