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.
