Answer 2

Answer:

25

Step-by-step explanation:

1. convert a and b in the bracket to their respective numbers (2+3)²

1. convert a and b in the bracket to their respective numbers (2+3)²2. now add 2 and 3= 5 and put its power= 5²

1. convert a and b in the bracket to their respective numbers (2+3)²2. now add 2 and 3= 5 and put its power= 5²3. as we know 5²= 5×5

1. convert a and b in the bracket to their respective numbers (2+3)²2. now add 2 and 3= 5 and put its power= 5²3. as we know 5²= 5×54. (5×5)= 25

1. convert a and b in the bracket to their respective numbers (2+3)²2. now add 2 and 3= 5 and put its power= 5²3. as we know 5²= 5×54. (5×5)= 25 Therefore, 25 is your answer
