Answer 1

a)√2^6=2^3=8
b)√11^6=11^3=1331
c)√19^4=19^2=361
d)√23^4=23^2=529
e)√3^8=3^4=81
f)√10^8=10^4=10000
g)√10^12=10^6=1000000
h)√(-3)^2=(-3)
i)√(-19)^4=(-19)^2=(-361)
j)√(-2)^6=(-2)^3=(-8)
k)√(-10)^14=(-10)^7=(-10000000)
l)√2^2×√3^4=2×9=18
m)√3^6×√5^4=27×25=675
n)√2^2×√3^4×√5^6=2×9×125=2250
o)√(-3)^2×√(-5)^4×(-7)^2=(-3)×(-25)×(-7)=(-525)
p)√5^2×√(-2)^8×(-3)^4=5×(-16)×(-9)=720
q)√(-4)^2×(-5)^4×(-1)^2012=(-4)×(-25)×(-1)=(-100)
r)√(-2)^10×(-3)^6×(-1)^100=(-32)×(-27)×(-1)=(-864)
