Rewrite the expression to make it true:

[tex]\[2^{-5}=\frac{1}{2^{\square}}=\frac{1}{\square}\][/tex]


Sagot :

To solve the expression \(2^{-5}\), let's break it down step-by-step:

1. Understanding the Negative Exponent:
The expression \(2^{-5}\) involves a base of 2 raised to a negative exponent, -5. A negative exponent indicates a reciprocal. Specifically, \(2^{-5} = \frac{1}{2^5}\).

2. Calculating the Positive Exponent Term:
Next, we need to determine what \(2^5\) equals. This involves multiplying 2 by itself 5 times:
[tex]\[ 2^5 = 2 \times 2 \times 2 \times 2 \times 2 \][/tex]
[tex]\[ 2 \times 2 = 4 \][/tex]
[tex]\[ 4 \times 2 = 8 \][/tex]
[tex]\[ 8 \times 2 = 16 \][/tex]
[tex]\[ 16 \times 2 = 32 \][/tex]

3. Substituting Back to the Reciprocal Form:
Now that we know \(2^5 = 32\), we can substitute this into our original reciprocal expression:
[tex]\[ 2^{-5} = \frac{1}{2^5} = \frac{1}{32} \][/tex]

So, filling in the blanks in the given expression:
[tex]\[ 2^{-5} = \frac{1}{2 \cdot 2^4} = \frac{1}{32} \][/tex]

Thus,
[tex]\[ 2^{-5} = \frac{1}{32} \][/tex]

Therefore, the answer is:
[tex]\[ 2^{-5} = 0.03125 \quad \text{and} \quad 2^5 = 32 \][/tex]

The solution shows the value of both the negative and positive exponentiation:
[tex]\[ 2^{-5} = 0.03125 \\ 2^5 = 32 \][/tex]
