Evaluate the following expression when r = 2 and t = 5.
(2r)^t - 2
a. 1022
b. 16
c. 64
d. 62
(2r)^t - 2
4^5 - 2
1,024 - 2 = ?
1022
Right.
To evaluate the expression (2r)t - 2 when r = 2 and t = 5, you need to substitute the values of r and t into the expression and then simplify it.
First, substitute r = 2 and t = 5 into the expression:
(2(2))(5) - 2
Next, perform the multiplication operations:
(4)(5) - 2
Now, perform the final multiplication and subtraction:
20 - 2 = 18
Therefore, the value of the expression when r = 2 and t = 5 is 18.
