How can you solve this equation?? It's precalculus

Question

jkristia · Answer

you need to isolate x, so subtract 3 form both sides, then divide by 7^5 on both sides.
Then you end with a value on the left and $$\sqrt{x^2}$$ on the right

jkristia · Answer

well, a negative 7^5 of course

anonymous · Answer

Firstly, sqrt(x^2) is x. After doing that, just rearrange the equation by isolating x and solving for it.

anonymous · Answer

ok

anonymous · Answer

After you get the answer, post it, and I'll tell you whether it's correct or not. @Powerful22

jkristia · Answer

obviously sqrt(x^2) is x, but I didn't want to give that away

anonymous · Answer

No that's incorrect @Powerful22

anonymous · Answer

Should I show you some first steps so you know how to start off? @Powerful22

jkristia · Answer

Are you actually supposed to fine the actual value ? or just show the how to solve for x ?.

$$\frac{ -2-3 }{-7^5 } = x = 0.000297$$

anonymous · Answer

@jkristia That is correct. But you should never give away the answer. Try to show the beginning steps so the asker actually understands the process of solving the question.

anonymous · Answer

No that's wrong @Powerful22

jkristia · Answer

can you show how you get 4.98 ?

anonymous · Answer

Well, i have 4 multiple choices and thought 0.43 would work, and you guys kept saying no, no, no, and no. U guys are trying to solve for x, which is not what i'm asking for or trying to learn for.

jkristia · Answer

usually 'solve the equation' means solve for x, and if possible, find the value for x.

anonymous · Answer

They want me to know the properties of exponent.

anonymous · Answer

how to use properties of exponents

anonymous · Answer

x= -5/16807 is not one of my choices.

anonymous · Answer

that's ok, @jkristia you can go hep other people. I closed my question. Thanks for help anyways.

jkristia · Answer

and what are the choices ?
I see this as $$x = \frac{-5}{-16807} = \frac{5}{16807}$$
but you are saying that is not one of the choices
