Answer:
84
Step-by-step explanation:
y = abˣ
20 = ab¹
20 = ab
b b
20/b = a
y = abˣ
4 = (20/b)b²
4 = 20b
20 20
¹/₅ = b
y = abˣ
20 = ¹/₅b¹
20 = ¹/₅b
¹/₅ ¹/₅
100 = b
y = abˣ
y = 100(0.2)ˣ
Answer:
The simplify form of the provided expression is:
Step-by-step explanation:
Consider the provided expression.

Now simplify the above expression as shown below:

as 16/8 = 2
Now again simplify the above expression.
as 2/6 = 1/3
Now, multiply the whole expression with 3.
Hence, the simplify form of the provided expression is:
