Two circular ponds at a botanical garden have the following radii. pond a. 5√(164 ) meters pond b. (25√200)/5 todd simplifies the radius of pond a this way: 5√(164 ) meters step 1: 5(√100+√64) step 2: 5(10+8) step 3: 5(18) step 4: 90 one of todd’s steps is incorrect. identify which step is incorrect; and rewrite the step so it is correct.

The correct step will be

Step-by-step explanation:

We have been given that pond A has a radius of meters and radius of Pond B is meters. Todd simplifies the radius of pond A and we are asked to find out error in Todd's steps.

Step 1:

Since we know that . We can see that Todd has made error in his very first step by splitting as .

The correct step will be,

Therefore, the correct step 1 will be: .  

Now let us simplify our given radical expression.

Therefore, our given radical expression simplifies to meters.
