Answer:
The value of given expression is 6.
Step-by-step explanation:
Given expression is;
[tex]\sqrt{5x^2-(-x^4)}[/tex]
We have to solve the expression when x = -2
Putting x = -2 in the given expression,
Solution = [tex]\sqrt{5(-2)^2-(-(-2)^4))}\\[/tex]
Solution = [tex]\sqrt{5(4) - (-16)[/tex]
Solution = [tex]\sqrt{20+16}[/tex]
Solution = [tex]\sqrt{36}[/tex]
Taking square root of 36
Solution = 6
Thus,
[tex]\sqrt{5x^2-(-x^4)}[/tex] = 6
Hence,
The value of given expression is 6.
