  1. Giải đáp: $x=\sqrt[3]{36-3^{16}}$
    Lời giải và giải thích chi tiết:
    Ta có:
    $x^3-2^3=2^5-(3^{16}+2^8:2^6)$
    $\to x^3-2^3=2^5-(3^{16}+2^{8-6})$
    $\to x^3-2^3=2^5-(3^{16}+2^2)$
    $\to x^3-8=32-(3^{16}+4)$
    $\to x^3-8=32-3^{16}-4$
    $\to x^3=32-3^{16}-4+8$
    $\to x^3=36-3^{16}$
    $\to x=\sqrt[3]{36-3^{16}}$
