Step-by-step explanation:
[2⁴/7⁴ × (7²/2³)⁴] ÷(7³/8² × -1)
[2⁴/7⁴ × 7 power 8 /2¹²] ÷ [7³/8² × -1]
2⁴/2¹² × 7 power 8 /7⁴ ÷ [7³/8² × (-1)]
2⁴-¹² × 7 power 8 -4 ÷ "
2 power -8 × 7⁴ ÷ "
(1/2 power 8 × 7⁴ × 8²/7³)
(7⁴×2 power 6 / 2 power 8 × 7³)
-(7⁴-³ × 2 power 6 - 8)
-(7¹× 2-²)
-(7/2²)
-7/4
Final answer is : -7/4
