When $n = 7$ $n=7$ , $n^{4} = 7^{4} = 7 \cdot 7 \cdot 7 \cdot 7 = 2401 .$ $n^4=7^4=7*7*7*7=2401.$
Similarly, when $n = 0.4$ $n=0.4$ , $n^{4} = {(0.4)}^{4} = (0.4) \cdot (0.4) \cdot (0.4) \cdot (0.4) = 0.0256 .$ $n^4=(0.4)^4=(0.4)*(0.4)*(0.4)*(0.4)=0.0256.$

Explanation:

When $n = 7$ $n=7$ , $n^{4} = 7^{4} = 7 \cdot 7 \cdot 7 \cdot 7 = 2401$ $n^4=7^4=7*7*7*7=2401$
Similarly, when $n = 0.4$ $n=0.4$ , $n^{4} = {(0.4)}^{4} = (0.4) \cdot (0.4) \cdot (0.4) \cdot (0.4) = 0.0256 .$ $n^4=(0.4)^4=(0.4)*(0.4)*(0.4)*(0.4)=0.0256.$
