    (4v - 3w) ²

    (4v - 3w) (4v - 3w)

    4v (4v - 3w) - 3w (4v - 3w)

    4v (4v) - 4v (3w) - 3w (4v) - 3w (-3w)

    16v² - 12vw - 12vw + 9w²

    16v² - 24vw + 9w²

    (4v-3w) ∧2, Its to the second power so take the exponent 2 and put it on the variables and coefficients so you would have (4∧2) (v∧2) - (3∧2) (w∧2). Then you would do the math and get 16v∧2-9w∧2 than you would add the like terms so you have 25v∧2w∧2.
