  1. 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

    what is the square root of 5z-2, then it says plus 7=10 First, subtract 7 from each side so you now have: sqrt(5z-2)=3. Then square each side, so you now have: 5z-2=9. Then add 2 to each side so you have 5z=11. Then divide each
