To simplify the expression 4^-3 × 4 × 4^-5 in exponential form with positive exponents only, we can combine the terms that have the same base, which in this case is 4.
First, we can rewrite 4^-3 as 1/4^3 and 4^-5 as 1/4^5. Then, we combine the terms:
1/4^3 × 4 × 1/4^5
Now, let's simplify each term:
1/4^3 = 1/64
1/4^5 = 1/1024
Substituting these values back into the expression:
1/64 × 4 × 1/1024
Next, we can multiply 1/64 by 4:
1/16 × 1/1024
Finally, we can multiply these two fractions together:
1/16384
Therefore, 4^-3 × 4 × 4^-5 simplifies to 1/16384.
