In algebra, do I multiply exponents or add an exponent to a number when distributing a variable to another variable?

Yes, when distributing a variable to another variable in an algebraic equation, you multiply the exponents or add an exponent to the number. For example, when you multiply x and x^2, the product would be x^3. When you multiply 2z and 3z, the product would be 6^2. (When you multiply two variables with no exponents, you are essentially squaring the number.)

answer: i think it is (1,-2)

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
