Question

Evaluate the expression when x = 6 and y = 2: 2^(x + y) - 1.

Options:

Option 1: 22
Option 2: 18
Option 3: 8
Option 4: 64

Answer 1

To evaluate the expression 2^(x + y) - 1 when x = 6 and y = 2, substitute the values of x and y into the expression and calculate the exponent.

Step-by-step explanation:

To evaluate the expression when x = 6 and y = 2, we substitute the values of x and y into the expression:

2^(x + y) - 1 = 2^(6 + 2) - 1

Calculating the exponent, we get:

2^8 - 1 = 256 - 1 = 255

So, the answer is 255.
