e) -4√3×√7=
f)6√5 × (-√5 supra30)
g) 1,(4)√75×(-2,4√50) (-1Supra26√18)

Answer 1

a) 2√3×4√6=8√3*√6=8√3*6=8√18=8*3√2=24√2
b)2√3 ×(-√2)= -2√6
c) (-2√2)/(3 × √2/4)= -4/3
d) (-2√3) (-√3/2)=[-2(-√3)*√3]/2=√3*√3=√9=3
e) -4√3×√7= -4√21
f)6√5 × (-√5/30)= -(6√5*√5)830= -(√5*√5)/5=-5⁰= -1
g) 1,(4)√75×(-2,4√50) (-1/26√18)=-40/13√3=(-40√3)/39
    1,(4)=4/9
    -2,(4)=4/10
