Evaluate ab for a=6 and b=-9.
To evaluate ab for a=6 and b=-9, we simply substitute the values of a and b into the expression.
ab = 6 * (-9) = -54
Therefore, ab is equal to -54 when a=6 and b=-9.
To evaluate ab, you simply multiply the values of a and b.
Given a = 6 and b = -9,
ab = 6 * (-9)
Calculating the product, we get:
ab = -54
Therefore, ab = -54 when a = 6 and b = -9.
