Write 8^3 x (6^1/2) / (32^3/2) in the form a x square root b where a and b are integers.

Start by finding out what 8 cubed is then find the value of 32 3/2 in surd form. Then see if u can write 6^1/2 in surd form. Write all this as one fraction and see if u can simplify it. You should be able to find the answer. If not, feel free to ask
