%288a%5E2b%5E3%29%2F%283k%29=4a Start with the given equation.


8a%5E2b%5E3=4a%283k%29 Multiply both sides by 3k.


8a%5E2b%5E3=12ak Multiply 4 and 3 to get 12


8a%5E2b%5E3=12ak Divide both sides by 12a.


%288a%5E2b%5E3%29%2F%2812a%29=k Divide both sides by 12a.


%282%2A2%2A2%2Aa%2Aa%2Ab%5E3%29%2F%2812a%29=k Expand 8a%5E2 to get 2%2A2%2A2%2Aa%2Aa


%282%2A2%2A2%2Aa%2Aa%2Ab%5E3%29%2F%282%2A2%2A3%2Aa%29=k Expand 12a to get 2%2A2%2A3%2Aa
