what does this equation mean: 10 to the -3 power?
how do you solve it?
i know that 10 to the 3 power id 1000.
but how do you do -3 power?

10ֿ³ = 0.001
it is the same as 1 divided by 1000
1 / 1000 = 0.001
- - - - - - - -s-

The answer is .001 you move the decimal to the right but this only works with ten to a negative power
other than that say you had 5 to the -2 power it becomes 1 (numerator) over 5 to the second power (denominator)

anything to a negatie power is the same as saying... well its hard to explain lol but lemme show you an example.
2^(-2) = 1/2^2
it just drops down to the denom and becomes a postiive exponent.
since its 10^ to the neg 3 power, the answer would be 1/1000.
hope this helps!

It is 0.001
Instead of moving the decimal point to the right 3 places for 10^3...you move the decimal point to the left 3 places for 10^-3
Good luck!

when you have a negative exponent, you take the inverse of the base and take the same but positive exponent
a^-n = (1/a)^n
(10)^-3
the inverse of the base 10 is 1/10. And take the positive exponent
(1/10)^3
= 1/1000
hope this helps
