A negative exponent is exactly the same as a positive one with one major exception: a negative power means divide 1 by that number. Sounds complicated but if you see it it's much simpler.
2=2/1
25=25/1
2^2=(2^2)/1
25^2=(25^2)/1
2^-2=1/(2^2)
25^-2=1/(25^2)

What do they mean by a to the b power times a to the c power equals a b c power?
ab*ac=ab+c consider the powers of 2. 22=4, 23=8, 22*23=32=23+2=25 when multiplying a number by itself, you raise its power by one. when multiplying a number by itself n times, you raise it to the power of n, so if you raise a number to the power n, then the seame number to the power m, then multiply these together you are multiplying n+m times
Is negative 9 a natural number?

What number is greater 10 to the power 390?
If you mean "greater than", you can raise it to a higher power.
What does it mean to have the negative powers of ten?
Negative power of10 is a number which is 10% of its previous number. Like 10 power -1 = 0.1 10 power -2 = 10% of 0.1=0.01 10 power -3 = 10% of 0.01=0.001

Is five negavite two is a positive or negative number?
I am going to say positive. If it is 5 -2 well that is 3, which is positive. Possibly you mean 5 with a small -2 slightly raised after it. That means 5 raised to the power of -2. Any time you have a negative exponent, you can take the reciprocal, and make it positve. So 5^-2 {the ^ symbol means to raise the power of} can be rewritten as 1/(5^2), which is 1/25. And this is a positive number as well.
Can power be a negative number?
Yes. -2^3, for example, is -8. This question is ambiguous - the questioner may mean "can the exponent be negative". In which case 2-3 is 1/8 or 0.125.
What are negative intergery exponents?
I assume you mean "negative integer exponents".It means that: * It is an exponent * It is an integer (whole number) * It is negative (less than zero, i.e., with a minus sign) A negative exponent is defined as the reciprocal of the positive exponent. For example, 10 to the power -5 is the same as 1 / (10 to the power 5).
What is 5 to the power of negative?
