Hello from MrBillDoesMath!
Answer:
3,8
Discussion:
Let "n" and "p" be the two positive integers. Then
n = p - 5 (*)
and
np = 24 (**)
Substituting (*) in (**) gives
np = 24 => as p = n+5
n(n+5) = 24 =>
n^2 + 5n - 24 = 0 => factor polynomial (n+8)(n-3)
So n = 3 or -8 but as n is positive, n = 3 Then p = n + 5 = 8
Check:
Is n (3) 5 less than p (8). Yes
Does np = 3 *8 24. Yes
Thank you,

Answer:
√1
Step-by-step explanation:
If you do the fractions by squaring them then you get fractions that equal 1:
5/13^2 = 25/169
12/13^2 = 144/169
144/169 + 25/169 = 169/169 = 1
√1
