  • (^9√ ̅16)^5

    = (^9√ ̅2^4)^5

    = (2^(4/9))^5

    = (2^(1/9)^4)^5

    = (^9√ ̅2)^(4*5)

    = (^9√ ̅2)^20

    10^(3/7) = (^7√ ̅10)^3

    (8x^3y^2)^-3

    = (2^3*x^3*y^2)^-3

    = (2^3*x^3*y^2)^-3

    = 2^(3-3)*x^(3-3)*y^(2^-3)

    = 2^0*x^0*y^(-1)

    = 1*1*y^(-1)

    = 1/y

    x^3 + 4x^2 + 9x + 36

    -3, -2, -1, 1, 2, 3

    x^3 + 4x^2 + 9x + 36

    = x^2(x + 4) + 9(x + 4)

    = (x^2 + 9)(x + 4)

    x = -4 or x = ±√ ̅(-9) = ±3i
