Hi All,
Just took my first GMAT Prep practice test and scored a 620 (41V, 32Q).
Some of the quant questions I missed that I could not figure out after reviewing are attached. ANY HELP you can provide regarding the correct solution is appreciated.
I will definately return the favor as I improve!

Q -3
box 9 = 27
box 6 = 3
box 9* box 8 = 81 = box 27
Q-5
angle abc = 90 degrees
u know BC and AC as 1 and 2 respetively
so u can find AB
q-7
angle ADB = 180-2x
therefore angle ABD = 180-x -(180 -2x)
=x
so AD = BD but we know know BD = BC so only A is necessary

(1/5)^m*(1/4)^18=(1/(2)(10)^35
What is m
TAking evrything to numberator
5^-m * 2 ^36 (using 4=2*2) = 2^-1 * (2*5)^-35 (using 10=2*5)
=>2^-1*2^-35*5^-35
5^-m*2^-36=2^(-1-35)*5^-35
Cancel out 2^-36 from both the sides
5^-m=5^-35
-m=-35
m=35
