Respuesta :
We don't really need the restriction. One part of the definition of
[tex] \sqrt a [/tex]
is that when it's squared, we'll get [tex] a [/tex]
[tex](\sqrt a)^2 = a[/tex]
Answer: a
For any nonnegative real number a, [tex]\rm (\sqrt{a})^2=a[/tex] and this can be determined by using the arithmetic operations.
Given :
Nonnegative real number 'a'.
The following steps can be used in order to evaluate the given expression:
Step 1 - The arithmetic operations can be used in order to evaluate the given expression.
Step 2 - Write the given expression.
[tex]\rm =(\sqrt{a})^2[/tex]
Step 3 - Simplify the above expression by opening the square root.
[tex]\rm (\sqrt{a})^2=(a)^{\frac{1}{2}\times 2}[/tex]
Step 4 - Further, simplify the above expression.
[tex]\rm (\sqrt{a})^2=a[/tex]
