Answer:
64in2
Step-by-step explanation:
3+8+3=14
4+4=8
14x8=112
3x4=12
12x4=48
112-48=64
(4 sqrt. 3) /4
Sqrt. 3 is the tangent of a because opposite over adjacent.
1. Change both numbers to common base.
2. Use quotient rule 
e)
You can write 9 as 3², then both numbers have the same base.
, where x is the exponent
I cannot really see the exponents because picture is bad quality.




You want to replace x and y with actual numbers, but as I said the picture is too bad.
f)
Convert to base 4, then quotient rule.
g)
Use the quotient rule, you already have same base.
h)
Convert to base
, then quotient rule.
