Math For you guys!!!!
 

Lets see who can do this stuff =] (good luck)


1. If 1/2x +1/2(1/2x + 1/2(1/2x +1/2(1/2x + ... = y,
then x = ?

2. y = log x
If y = 10, then what is x?

3. 10*9*8*7*6*5*4*3*2*1 = 10!
Can this be true?! Why or why not?



HAVE AT IT GUYS!!!!

ANSWERS!!!!

1. If x = 1,
then the equation likes this:
1/2 +1/2(1/2 + 1/2(1/2 +1/2(1/2 + ... = y
1/2 +1/4 + 1/8 + 1/16 + 1/32 + ... = y
y = 1 = x
y = x

2.y = log x
10 = log x
10 = 10^x
x = 1

3.Yes!!!
The expression "x!" means x(x-1)(x-2)(x-3)...1
So 10! means 10(10-1)(10-2)(10-3)(10-4)(10-5)(10-6)(10-7)(10-8)(10-9)=
10*9*8*7*6*5*4*3*2*1=10!,
which means it is correct.


Highlight for answers good luck!
