Answer :

To solve for \(n\) in the equation \(\sqrt{4^n} = 1024\), follow these steps:

1. Isolate the exponential term: Start with the given equation.
[tex]\[ \sqrt{4^n} = 1024 \][/tex]

2. Square both sides: Eliminate the square root by squaring both sides of the equation.
[tex]\[ (\sqrt{4^n})^2 = 1024^2 \][/tex]

Simplifying this, we get:
[tex]\[ 4^n = 1024^2 \][/tex]

3. Calculate the right-hand side: Calculate \(1024^2\).
[tex]\[ 1024^2 = 1048576 \][/tex]

4. Equate the expressions: Now we have the equation:
[tex]\[ 4^n = 1048576 \][/tex]

5. Expressing \(4\) as a power of \(2\): Note that \(4\) can be written as \(2^2\). Therefore:
[tex]\[ 4^n = (2^2)^n = 2^{2n} \][/tex]

6. Rewrite the equation: Substitute \(2^{2n}\) for \(4^n\), giving us:
[tex]\[ 2^{2n} = 1048576 \][/tex]

7. Expressing \(1048576\) as a power of \(2\): Calculate the power of 2 that equals \(1048576\). We find that:
[tex]\[ 1048576 = 2^{20} \][/tex]

So, the equation becomes:
[tex]\[ 2^{2n} = 2^{20} \][/tex]

8. Equate the exponents: If the bases are equal, the exponents must also be equal. Therefore:
[tex]\[ 2n = 20 \][/tex]

9. Solve for \(n\): Divide both sides of the equation by 2:
[tex]\[ n = \frac{20}{2} = 10 \][/tex]

Hence, the value of \(n\) is:
[tex]\[ n = 10 \][/tex]
