Step-by-step explanation:
log243(81)=4/5
81=243^4/5

Answer:
1 2/4
Step-by-step explanation:
3/4 doubled is 
Now, 
on simplification.
Therefore,
3/4 doubled is 1 2/4
the answer is 4.5 ft
Step-by-step explanation:
Step-by-step explanation:
Given that the two fugures in the question above are similar, it means they have the same shape, even though they are if different sizes, the ratio of their corresponding sides are proportional. Thus,
18/x = 8/2
Let's solve for x as required.
We have,
18/x = 8/2
=>Cross multiply:
18 × 2 = 8 × x
36 = 8x
=>Divide both sides by 8
36/8 = x
4.5 = x
x = 4.5 ft
