Answer:

4)Add the exponents and keep the same base. Then find the reciprocal and change the sign of the exponent

Step-by-step explanation:

The question can be written as

(2³)(2⁻⁴)

Apply laws of indices, Keep the same base and add the exponents

[tex]2^3*2^{-4} \\\\\\2^{3+-4} \\\\\\2^{-1} \\\\[/tex]

This can be expressed as;

[tex]2^{-1} \\\\=\frac{1}{2^1} \\\\=\frac{1}{2} \\\\\\=0.5[/tex]
