Answer:
No, he is going to have $496, which is $4 dollars less than what he wanted.
Step-by-step explanation:
(-1) to the power of an even number is +1.
(-1) to the power of an odd number is -1.
Since 50 is an even number, (-1)⁵⁰ = 1.
60 divided by 5,
is 12.
In which case,
12 times 3...
Is 36$.
So Leo would pay 36$ for 3 DVDs at the rate of 12$ for each DVD
3^2 = 9 = 4+5
5^2 = 25 = 12+13
work:
If you want to write an odd number as the sum of two consecutive integers, just subtract 1 then divide by 2 and you'll get the first integer.
Like with 25: first subtract 1 and get 24. Then divide by 2 and get 12. So the integers are 12 and 13.
