Percentage
A percentage is a number indicated as a fraction of 100. It is a dimensionless number often expressed using the symbol %.
Algebraic Expressions
In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.
Numbers
Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.

What is b?
![In this educational setting, we explore an interesting mathematical expression. The equation given in the image is:
\[
\sqrt{4^a} \cdot \sqrt{4^b} = 2^{b}
\]
Explanation:
- The term \(\sqrt{4^a}\) represents the square root of \(4\) raised to the power of \(a\).
- The term \(\sqrt{4^b}\) represents the square root of \(4\) raised to the power of \(b\).
To further understand, let’s simplify both square root terms:
\[
\sqrt{4^a} = (\sqrt{4})^a = 2^a
\]
\[
\sqrt{4^b} = (\sqrt{4})^b = 2^b
\]
Thus, the equation now becomes:
\[
2^a \cdot 2^b
\]
Using the properties of exponents, we know that:
\[
2^a \cdot 2^b = 2^{a+b}
\]
Therefore, the given equation can be simplified to:
\[
2^{a+b} = 2^b
\]
For the equality to hold true, \(a + b\) must be equal to \(b\). Therefore:
\[
a + b = b
\]
Subtract \(b\) from both sides:
\[
a = 0
\]
This shows that the simplest solution to the equation is when \(a = 0\). This mathematical expression is a good example of exploring the properties of exponents and square roots.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F9597aabe-047a-417f-a2e0-78440e121371%2Fdc919bc9-0359-4f11-99db-0c6aab981dea%2Fndv3n3_processed.jpeg&w=3840&q=75)
