Explanation
We begin by converting the right hand expression, ie., \( (\frac{1}{2})^{4} \). This involves raising
to the power
. Plugging this into a calculator or calculating manually, it gives:
Then, we equate
to
. The negative notation of the exponent signifies the reciprocal of the value or base (which is `n` in this case). This means
. Eastings, this means that
.Finally, to get the value of
, we need to get rid of the
exponent. We do this by raising both sides to the power of
, which gives \( n^{(4/5 * 5/4)} = n^1 = n \). This implies
Calculating
, we get the accurate answer:
