given that l=-2, m=3 and n=7 calculate the value of: lm(m-n)
(2*3)(3-7)
(6)(-4)
-24
To calculate the value of lm(m-n), we need to substitute the values of l, m, and n into the expression.
First, substitute l = -2, m = 3, and n = 7 into the expression.
lm(m-n) = (-2)(3)(3-7)
Next, simplify the expression inside the parentheses.
= (-2)(3)(-4)
Now, perform the multiplication.
= -6*(-4)
When multiplying two negative numbers, the result is positive.
= 24
Therefore, the value of lm(m-n) is 24.
