Final answer:
0.8 to the fourth power equals 0.4096, which is the result of multiplying 0.8 by itself four times.
Step-by-step explanation:
To calculate 0.8 to the fourth power, you need to multiply 0.8 by itself four times. This looks like (0.8) × (0.8) × (0.8) × (0.8). When you do that,
(0.8) × (0.8) = 0.64, and then (0.64) × (0.8) = 0.512,
finally (0.512) × (0.8) = 0.4096. So, 0.8 to the fourth power equals 0.4096.
