What is the value of 12x^-3y^1 for x=-1and y=5?
Substituting x=-1 and y=5 into the expression 12x^-3y^1, we get:
12(-1)^-3(5)^1
= 12(-1/1,000)(5)
= -0.06
Therefore, the value of 12x^-3y^1 for x=-1 and y=5 is -0.06.
To find the value of 12x^(-3)y^(1) when x = -1 and y = 5, we can substitute these values into the expression.
First, consider x = -1:
12(-1)^(-3)y^(1) = 12/(-1)^3 * y^(1)
Next, consider y = 5:
12/(-1)^3 * 5^(1) = 12/(-1) * 5
Simplifying further:
12/(-1) * 5 = -12 * 5
Finally:
-12 * 5 = -60
Therefore, when x = -1 and y = 5, the value of 12x^(-3)y^(1) is -60.
