Answer:
270000
Step-by-step explanation:
its simple math
2n^2-20=0
2n^2=20
n^2=20÷2
n^2=10
n=radical 10
X+5/2-x+3/6=1
make the fractions have the same denominator
x+15/6-x+3/6=1
18/6=1
3=1 so the equation is not true
Answer:3
Step-by-step explanation:r( cos Ф + i sinФ) is the fifth root of 243(cos 240 + i sin 240), then r^5( cos Ф + i sin Ф )^5 = 243(cos 240 + i sin 240).
