This is a good question, and also easy...
BY THE WAY .... YOUR QUESTION SHOULD LOOK LIKE:
[tex] \sqrt[3]{375} -4 \sqrt[3]{3} [/tex]
The idea is that you need to factor the number 375 to its multiples and extract all possible factors from the cube root ....... as follows
375 = 3 * 5 * 5 * 5 = 3 * (5)^3
then:
[tex] \sqrt[3]{375} = \sqrt[3]{3*5^3} =5 \sqrt[3]{3} [/tex]
Now you are able to subtract two similar terms:
[tex]\sqrt[3]{375} -4 \sqrt[3]{3}= 5\sqrt[3]{3} -4\sqrt[3]{3}=\sqrt[3]{3}(5-4)=\sqrt[3]{3}[/tex]
I hope that
helps!
