Respuesta :
Rule for when multiplying similar bases with exponents is:
(b^c)*(b^d)=b^(c+d)
In this case:
(10^3)*(10^-3)
10^(3-3)
10^0
1 (anything raised to the zero power is equal to one)
(b^c)*(b^d)=b^(c+d)
In this case:
(10^3)*(10^-3)
10^(3-3)
10^0
1 (anything raised to the zero power is equal to one)
