Answer:
150
Explanation:
First, we can simplify 5³:
5³ = 5 × 5 × 5 = 125
Then, we can simplify 4²:
4² = 4 × 4 = 16
Next, we can simplify √81:
√81 = √(9 × 9) = 9
Finally, we can add these simplified values:
5³ + 4² + √81
= 125 + 16 + 9
= 150

Note:
An exponent shows how many times its base (the big number next to it) should be multiplied by itself.
A square root gives the number that is multiplied by itself to get the number under the root sign.
