simpify: 3radical27x^10/5x^3y^5
7radical2x+2radical72x^3-radical162x^5
sorry don't know how to do the radical sign.
You will also have to insert brackets to clarify the order of operation here
e.g. I will do the 2nd one
assuming you meant:
7√(2x) + 2√(72x^3( - √(162x^5)
= 7√(2x) + 2√(2x) √(36x^2) - √(2x) √(81x^4)
= 7√(2x) - 12x√(2x) - 9x^2√(2x)
= √(2x) ( 7 - 12x - 9x^2)
clarify the first using brackets
