Step-by-Step Solution

To solve the exercise 52−41= 5^2-4^1= , we need to follow the order of operations, specifically focusing on powers (exponents) before performing subtraction.

  • Step 1: Calculate 52 5^2 . This means we multiply 5 by itself: 5×5=25 5 \times 5 = 25 .

  • Step 2: Calculate 41 4^1 . Any number to the power of 1 is itself, so 41=4 4^1 = 4 .

  • Step 3: Subtract the result of 41 4^1 from 52 5^2 : 25−4 25 - 4 .

  • Step 4: Complete the subtraction: 25−4=21 25 - 4 = 21 .

Thus, the correct answer is 21 21 .

Answer
