Answer:
1. (5×4)⁴ = 20⁴ = 20×20×20×20 = 400×400 = 160000
2. (6²)³ = 6²°³ = 6⁶ = 6×6×6×6×6×6 = 216×216 = 46656
3. 7²×3⁴ = 7×7 × 3×3×3×3 = 49×81 = 3969
4. (2×2)⁴ = 4⁴ = 4×4×4×4 = 16×16 = 256
5. 9²×9² = 9^(2+2) = 9⁴ = 9×9×9×9 = 81×81 = 6561
Step-by-step explanation:
#1 and #4 can also be 5⁴ × 4⁴ and 2⁴ × 2⁴, respectively, by using the Laws of Exponents. (Power of a Product Rule of Exponents)
That's all. Hope you get a perfect score.
