Answer:
1.25 : 1
0.25 : 1
Step-by-step explanation:
Ratios are basically fractions and proportions
10 : 8 is equal to 10/8 or 1.25/1, so 1.25 : 1
5 : 20 is equal to 5/20 or 0.25/1, so 0.25 : 1
According to order of operations rules, exponentiation must be done first. Thus, we have
(3^2)*(3^2) = (9)(9) = 81.
Alternatively, note that there's only one base (3) here, even tho' it shows up more than once. So, 3^2*3^2 = 3^(2+2) = 3^4 = 81.
