Step-by-step explanation:

 {({2}^{ - 1}  +  {4}^{ - 1}  +  {6}^{ - 1} +  {8}^{ - 1})}^{n}  = 1 \\  =  >  {(\frac{1}{2}  +  \frac{1}{4}  +  \frac{1}{6}  +  \frac{1}{8})}^{n}  = 1 \\  =  >  {( \frac{12 + 6 + 4 + 3}{24}) }^{n}  = 1 \\  =  >  {(\frac{25}{24})}^{n}  = 1 \\ Now ,\: we \: know \: any \: number\: with \\  power \: zero = 1 \\ So ,\: we \: put \:( n )\: as \: 0. \\  \\  =  >  { (\frac{25}{24} )}^{0}  = 1 \\  =  > 1 = 1 \\  \\ Therefore \:  \:  \: LHS  = RHS\\  \\ Hope \: it \: helps \: you ...... \\ Please \: mark \: my \: answer \: as \\ brainleist......

Step-by-step explanation:

[(2^-1)+(4^-1)+(6^-1)+(8^-1)]^n = 1

=>1/2+1/4+1/6+1/8=(12+6+4+3)/24

=>25/24^0=1

there fore,n =0
