-10^x=1000
how to find x ?

 

[Quzy]

x = 5?

 

[axas]

x = 5?

-10^5=-100000

 

[Zogaroth]

that-that.. thats impossible :s

 

[Prest]

Homework? lol

 

[Prest]

Homework? lol

Edit: -10 to the 3rd power

 

[Zogaroth]

Homework? lol

Edit: -10 to the 3rd power

that is -1000

 

[Quzy]

-10^5=-100000

10^5= 100000

-10^5=10000


my bad x.x

 

[Prest]

Woops i meant -10 to the NEGATIVe 3rd power.

 

[Zogaroth]

-10^5=10000

-10*-10*-10*-10*-10=-100000

Woops i meant -10 to the NEGATIVe 3rd power.

that is -0.001

using wolfram I get this

how to find x ?

it's 1000 not fcking 100000 so I repeat... -10 to the negative 3rd power

 

[axas]

I'll make it easier for you and myself and post the exercise itself and ask how to do it step by step. I know the answer but dunno the process

 

[Prest]

it's -10 to the -3rd power, how to find out? -10 * -10 * -10 = 1000

 

[Zogaroth]

it's -10 to the -3rd power, how to find out? -10 * -10 * -10 = 1000

are you trolling us?

-10*-10=100
100*-10=-1000

 

[Prest]

Oh shet I did something wrong with my calculator, ahah never mind then

 

[Resource]

-10^x=1000
how to find x ?

(-10)^x=1000
(-10)*(-10) = 100 (right?)

I dunno, something like that..

This website will solve everything.

 

[Worr]

Did you start with imaginary numbers yet? I think you can solve those equations with no real answers using i since i*i = -1 but I don't remember how. But for example squareroot of -4 = 2i.

I think 'X' is infront of 'W' and behind 'Y'

how to find x ?

Might be wrong, a while since I did anything with logarithms.

-10^x = 1000

x = lg(1000)/lg(-10)
