The answer:
the main rule:
for all value positive of a real b, √b²= b, and √b*c= √b * √c, if c is a real positive
let A=√25x^4, we know that 25x^4=5² * x² * x²
therefore,
√25x^4= √5² * x² * x² =√5² √x² √x² = 5* x*x= 5x²
the final answer is A=√25x^4=5x²

Step-by-step explanation:
Answer:
The approximate area is A) 5.09cm²
Step-by-step explanation:
Area of a Circle = πr²
r = 1.8
Plug in our values
π(1.8cm²)
Evaluate the area of the entire circle
a = π(1.8cm²)
a = π(3.24cm)
a = 10.179cm²
Area of a sector, with the area of the circle of the sector being a = theta/360 * a
Evaluate the area of the sector
180/360*10.719cm²
0.5 * 10.179cm²
5.0895cm²
Round the value up
5.09cm²
