#5^2 - 2^4= color(green)(9#

#5^2 = 5 times 5 = 25#

#2^4 = 2 times 2 times 2 times 2 = 16#

#5^2 - 2^4 = 25 - 16 = color(green)(9#

To simplify (5^2 - 2^4), first calculate the exponents:

(5^2 = 5 \times 5 = 25) (2^4 = 2 \times 2 \times 2 \times 2 = 16)

Then, subtract (16) from (25):

(25 - 16 = 9)

So, (5^2 - 2^4 = 9).
