4

To evaluate the expression 3^x+6-y when x = 2 and y = 5, we substitute the values of x and y into the expression and simplify:

3^2 + 6 - 5

This simplifies to:

9 + 6 - 5

The sum of 9 and 6 is 15:

15 - 5

The difference between 15 and 5 is 10:

10

Therefore, the result is 10.

To evaluate the expression 3^x+6-y when x = 2 and y = 5, let's substitute the given values into the expression:

3^2 + 6 - 5

Simplifying the exponent:

9 + 6 - 5

Performing addition and subtraction:

15 - 5

The result is:

10

To evaluate the expression 3^x + 6 - y, we can substitute the given values of x and y into the expression and simplify it.

Given: x = 2, y = 5

Substituting these values into the expression:
3^2 + 6 - 5

Now, let's evaluate each part of the expression:

3^2 = 3 * 3 = 9
6 - 5 = 1

Now we can substitute the evaluated values back into the expression:
9 + 1

Adding both values together:
9 + 1 = 10

Therefore, the value of the expression 3^x + 6 - y when x = 2 and y = 5 is 10.
