7 evaluates the expression a2 + b.
option a.7 is the correct choice which evaluates the given expression.
Given values are a = 2 and b =3
the given expression is = a2 + b
To evaluate an expression, we first replace the variable with the given number, then we use the order of operations to simplify the expression.
Substitute these value in the given expression.
=2 × 2 ₊ 3
=7
Every time we replace the variables with its values we get the answer as 7. The other options present does not satisfy the equation.
For ex: 25 , we don't get this number when we substitute the given values in the expression. 10 is also not what we get when we solve the expression. Likewise other options are also invalid.
Hence we get the answer as 7.
