Evaluate the expression below for = 2 and t = 8.
4st^2-s^2
To evaluate the expression 4st^2 - s^2 for s = 2 and t = 8, we substitute the given values into the expression:
4st^2 - s^2 = 4(2)(8^2) - (2)^2
= 4(2)(64) - 4
= 512 - 4
= 508
Therefore, the value of the expression is 508 when s = 2 and t = 8.
To evaluate the expression 4st^2 - s^2 for s = 2 and t = 8, plug in these values into the expression:
4st^2 - s^2
= 4(2)(8^2) - (2)^2
= 4(2)(64) - 4
= 512 - 4
= 508
Therefore, when s = 2 and t = 8, the expression 4st^2 - s^2 evaluates to 508.
