Answer:
C
Step-by-step explanation:
a is defined first as 5. So a = 5.
b is defined after the circle b = -2
a^2 = 5^2 = 25
B^4 =(- 2)^4 = 16
Therefore sqrt(a^2 * b^4) = sqrt(25 * 16) = sqrt(400) = 20
The answer is C
20
We know that a = 5 and b=-2
The formula is[tex]\sqrt{a^{2}*b^{4}[/tex]
So we do 5 squared multiplied by -2 to the power of 4 and square root
[tex]\sqrt{5^{2}*(-2)^{4}[/tex]
Which is 20
