when dividing, just subtract exponents:
5^10 / 5^7 = 5^(10-7) = 5^3
because
5^10 = 5*5*5*5*5*5*5*5*5*5
5^7 = 5*5*5*5*5*5*5
divide, and seven of the 5's cancel, leaving only 3 in top: 5^3
76^11 / 76^5 = 76^(11-5) = 76^6
5^10 / 5^7 = 5^(10-7) = 5^3
because
5^10 = 5*5*5*5*5*5*5*5*5*5
5^7 = 5*5*5*5*5*5*5
divide, and seven of the 5's cancel, leaving only 3 in top: 5^3
76^11 / 76^5 = 76^(11-5) = 76^6
