Question

Introduceti factori sub radical:
2*5radical6=
4radical5=
3sub5 * radical10=
Scoateti factori de sub radical:
Radical18=
radical50=
5radical128=
radical350=
Va rog frumos

Answer 1

2*5radical6= 10*rad(6) =rad(10^2 *6) =rad(600)
4radical5= rad(4^2 *5) =rad(16*5)=rad(80)
3sub5 * radical10= nu stiu ce vrei sa zici cu 'sub'

Scoateti factori de sub radical:
Radical18 =rad(3^2 *2) =3*rad(2)
radical50=rad(5^2 *2) =5*rad(2)
5radical128= 5*rad(2^7)= 5* 2^3 *rad(2)=40*rad(2)
radical350=rad(7*5^2 *2) =5*rad(14)

Answer 2

[tex]4\sqrt5=\sqrt{4^2\cdot5} =\sqrt{16\cdot5} = \sqrt{80}\\\;\\ \sqrt{18} =\sqrt{9\cdot 2} =3\sqrt2\\\;\\ \sqrt{50}=\sqrt{25\cdot2} =5\sqrt2\\\;\\ \sqrt{350} =\sqrt{25\cdot14} = 5\sqrt{14}[/tex]
