Note that there are implied parentheses on that exponent expression 54, so simplify that too. I prefer to use fractions rather than decimals, so I'll convert to fraction form. Next, expand (or simplify) the exponents. (½)^{4 } is four factors of what is in the parentheses. Remember that 5! (read as "five factorial") is just 5 times 4 times 3 all the way down to 2. So expand the factorials so you can see the multiplication they are made from. Then you can cancel out common factors on the tops and bottoms and simplify them. This gives the final fraction of 5/32, which is equal to 0.15625. Hope this helps,
