tolongg bantu jawab!! sebagian udh aku jawab tapi takut salah.

1.(4³ × 2³)⁵  × 1/4² × (2²)³ = 4¹⁵ × 2¹⁵ × 1/4² × 2⁶
                                           = 4¹⁵ × 1/4² × 2¹⁵⁺⁶
                                           = 4¹⁵⁻² × 2²¹
                                           = 4¹³ × 2²¹
                                           = (2²)¹³ × 2²¹
                                           = 2²⁶ × 2²¹
                                           = 2²⁶⁺²¹ = 2⁴⁷
2.(4⁶/³ : 6³/²)² + (7⁵ 6⁴)(2 ⁶: 2⁴)/(3⁸ : 3²) ÷ 3²
    = (4⁴ : 6³) + (7⁵ 6⁴ 2²)/3⁶⁻²
    = (2⁸ : 2³ × 3³) + (7⁵.2⁴ × 3⁴.2²)/ 3⁴
    = (2⁵/3³) + (7⁵ 2⁶)
4. 2¹⁵ . 5²⁺³ / 5⁻² = 2¹⁵ . 5⁵⁻⁽⁻²⁾
                            = 2¹⁵ . 5⁷
5. 8² + 2³/².6²/² : 2⁴6² = 8² + 2³/² . 6¹ : 2⁴6²
                                    = 8² + 2³/²⁻⁴ . 6¹⁻²
                                    = 8² + 2⁻⁵/² . 6⁻¹
6. 3⁴ . 4⁻⁶ / 5⁻⁸ = (3⁴ . 5⁸)/4⁶
7. 2² × (2⁵)³/⁵ × (2⁷)³/⁷ = 2² × 2³ x 2³
                                     = 2²⁺³⁺³
                                     = 2⁸
