Write 1/2^1-n in non- fractional form.

Multiply numerator and denominator by

2^-(1-n):

1/2^(1-n) = 2^-(1-n)/1 = 2^(-1+n) =
2^(n-1)

Write 4+2x/x^-1in non fractional from

To write 1/(2^(1-n)) in non-fractional form, we can transform the expression using exponent rules.

First, let's rewrite the expression as 2^(-n+1).

Then, we can apply the exponent rule that states: a^(-b) = 1/(a^b).

Using this rule, we can transform 2^(-n+1) as 1/(2^(n-1)).

Therefore, 1/(2^(1-n)) in non-fractional form is 2^(n-1).

To write 1/2^(1-n) in non-fractional form, we need to simplify the expression.

To do this, we can use the exponent and rewrite the expression as 2^(-1+n).

Next, we can use the exponent rule that states a^(-n) = 1/a^n to rewrite the expression as 1/(2^(1-n)).

Finally, to put it in non-fractional form, we can rearrange the expression to get rid of the fraction:

1/(2^(1-n)) = (2^(1-n))^-1 = 2^(-1+n).

Therefore, 1/2^(1-n) in non-fractional form is 2^(-1+n).
