When the exponent blank is applied to a nonzero base, the result is always 1

zero (0)

when the exponent 0 is applied to a nonzero base, the result is always 1

Step-by-step explanation:

Acoording to the zero power rule, a non zero number raised to the power 0 is always 1:

whit

Let's check this property using an example:

We know that a quantity over itself is always 1:  

We also know that a base without exponent is always raised to the power 1:

Now, according to the division power rule , so

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:
