2)12²=144

3)9+144=153

Answer 2

Let's solve the expression step by step:

√(9² + 12²)

First, calculate the squares:

9² = 9 * 9 = 81 12² = 12 * 12 = 144

Now, the expression becomes:

√(81 + 144)

Next, add the numbers inside the square root:

√(225)

Finally, find the square root of 225:

√225 = 15

So, the expression √(9² + 12²) is equal to 15.
