White_wolf an IP address in not an email address. So using ur GFs email wont help when they ban you.
When an IP is banned, that is a number provided by your modem/router that modem/router cannot access this site...atleast that how i think it works.
And there are ways you can get around the ban and i think ARB is using those methods.

3.
log sqrt(232)
= .5 log 232
= 1.183

5. log sqrt(8)/log 8
= 0.5 log 10 (8)/ log 10 (8)
= 1/2
i think..

6. log 32 x = 0.8
32 ^0.8 = x
16 = x

8.
a) log 5 (5) = 1

b) log4 (9)
= log 10 (9)/ log 10 (4)
= 1.585

c) log 3 (2)
= log 10 (2) / log 10 (3)
= 0.631

1 * 1.585 * 0.631 = 1.000

9.
a^x = b^y
a)y log a (b) = x
log a (b) = x/y
log 10 (b)/ log 10 (a) = x/y
b)x log b (a) = y
log b (a) = y/x
log 10 (a)/ log 10 (b) = y/x

so i think the right answer is (3)

12. 16 ^ (log 4 (5))
16 ^ (log 10 (5) / log 10 (4))
= careless25 :D

13. If log 10 (7) = a
then log 10 (1/70) = a - 2a - 1
= -1.8451

14.
if log 27 = 1.431
then log 9 = 1.431/1.5
log 9 = 0.954
because 9 ^ 1.5 = 27

15. same reasoning as above

if log 10 (3) = .477
then 1000^ x = 3
log 1000 (3) = x
log 1000 (3) = .477/3
x = .159
because 10 ^ 3 = 1000

1. so make it a right angle triangle.

5cm base and 5 cm height.

so square root of 50 is the length of the side in centimeters.

That budgie looks exactly like the one i have.

Yup i did it!

49. Bhaskaracharya calculated the time taken by the earth to orbit the sun hundreds of years before the astronomer Smart. Time taken by earth to orbit the sun: (5th century) 365.258756484 days.

50. Although modern images of India often show poverty and lack of development, India was the richest country on earth until the time of British invasion in the early 17th Century. Christopher Columbus was attracted by India's wealth.

Heres some more:

1)
Ask you friend to think of a number.
Add 9 to this number.
Double the answer.
Add 3 to it.
Now multiply by 3.
Subtract 3 from the answer.
Divide by 6.
Subtract by original number.

The answer will always be 10
You can limit the friends choice by giving him only 1-100 to pick from, which will make calculation easier for him.

2)
Ask your friend to think of a number.
Multiply by 5.
Add 25 to it.
Divide it by 5.
Take the quotient and subtract it by original number.
Multiply by 3.

The answer will always be 15

3) A trick using the same concept in Ganeshs 2nd trick.

Create a table like this:

1   2   4   8   16   32
3   3   5   9   17   33
5   6   6   10  18  34
7   7   7   11  19  35
9   10 12  12  20 36

continue all the way to 63...
first column is all odd numbers
second column follows this pattern: +1 then +3, +1 then +3, etc...
Third column follows this pattern: +1, +1, +1,then +5, +1, +1, +1, then +5 etc...
Fourth column follows this pattern +1 * 7 then +9, +1 *7 then +9, etc...
Fifth : +1 * 15, then +19, +1 * 15, then +19 etc...
Sixth column : go all the way from 32 to 49 then skip 50 and go until 63.

After you have this table ready ask your friend/relative or stranger to point to the column his age shows up in.
Add up the numbers at the top of the columns indicated and the sum will be equal to his/her age.

For example if your friend is 12 years old.
He points to the 3rd and 4th column. You add up 4(top number of 3rd column) and 8(top No. of 4th Column) and you get 12.

Have fun!
