multiply powers with the same base : a^b * a^c = a^(b + c)....so basically, u keep the bases and add the exponents.
dividing powers with the same base : (a^b) / (a^c) = a^(b - c)....so basically, u keep the base and subtract the exponents
raising a power to a power : (a^b)^c = a^(b * c)...so basically, u multiply the exponents
