Answer:
The answer is 16.
Step-by-step explanation:
In this expression 4-2/2^-3, first of all we will solve the numerator.
Subtract 4 and 2
4-2= 2
So, the expression will become 2/2^-3
Now notice that the numerator has the base 2 and exponent 1 where as the denominator has the base 2 and exponent -3. Both the numerator and denominator have the same base
So we will use the property a^m/a^n=a^m-n.
=2/2^-3
=2^1-(-3)
=2^1+3
=2^4
2^4 means that 2 will be multiplied 4 times.
=2*2*2*2
=16
Thus the answer is 16....
