Evaluate: a+b^4 where a=2 , b=3 .

To evaluate the expression a+b^4 where a=2 and b=3, we substitute the values of a and b into the expression:

a+b^4 = 2 + 3^4

Simplifying further:

3^4 = 3 × 3 × 3 × 3 = 81

So, a+b^4 = 2 + 81 = 83

Therefore, when a=2 and b=3, the value of the expression a+b^4 is 83.
