Considering that it is allowed to repeat the digits in the three-digit code, we have,
10 x 10 x 10 ways
which is equal to 1000 ways.
For the scenario that only even numbers without repetition can be included, we have,
5 x 3 x 1 ways
which is equal to 15 ways.
The probability is therefore 15/1000 or 3/200.
7(h+k)(h+k- 3) if this is the answer you're looking for this is what I got so. Good luck
The answer:
the main rule:
for all value positive of a real b, √b²= b, and √b*c= √b * √c, if c is a real positive
let A=√25x^4, we know that 25x^4=5² * x² * x²
therefore,
√25x^4= √5² * x² * x² =√5² √x² √x² = 5* x*x= 5x²
the final answer is A=√25x^4=5x²

sorry i don't know the answer but are you an army ?
