It is: (-5-2) times -3 = +21
Yes, -5*10^-2 and it is equivalent to -0.05
That is the definition of negative powers.

(5-2) x (52) = (1/52) x (52) = 52/52 = 1

It is: (-5-2) times -3 = +21
Yes, -5*10^-2 and it is equivalent to -0.05
Negative 5 to the second power would be -5 times -5 which would be 25.
It is: 25
That is the definition of negative powers.
if a number is multiplied to a power like 5^2 it means 5 times itself that many times. Therefore if it is 5^-2, it is the opposite of 5^2 so one does the opposite of multiplying exponentially and divides exponentially.

It is: (8*10^-3) divided by (5*10^-5) = 160
