\[ \large \sqrt{45}=\sqrt{5\cdot9}=3\sqrt{5} \]

for the sqrt75 i got sqrt5*7*2
anonymous
  • anonymous
im stuck there
anonymous
  • anonymous
i think \(75=25\times 3\)
helder_edwin
  • helder_edwin
right
anonymous
  • anonymous
ohh..makes sense
anonymous
  • anonymous
making \(\sqrt{75}=\sqrt{25\times 3}=\sqrt{25}\times \sqrt{3}=5\sqrt{3}\)
helder_edwin
  • helder_edwin
now do the same with 192
helder_edwin
  • helder_edwin
\[ \large \sqrt{192}= \]
anonymous
  • anonymous
would it be 4sqrt6?
helder_edwin
  • helder_edwin
i got \[ \large \sqrt{192}=\sqrt{2^6\cdot3}=2^3\cdot\sqrt{3}=8\sqrt{3} \]
anonymous
  • anonymous
oh okay. i missed a 2
anonymous
  • anonymous
so how would i simplify all that?
helder_edwin
  • helder_edwin
now plug in everything: \[ \large \sqrt{45}-\sqrt{75}+\sqrt{192}=3\sqrt{5}-5\sqrt{3}+8\sqrt{3} \]
helder_edwin
  • helder_edwin
now combine like terms.

  • anonymous
do you add or multiply?
helder_edwin
  • helder_edwin
add or substract

  • goformit100
yeah

  • anonymous
okay thx

  • helder_edwin
\[ \large =3\sqrt{5}+3\sqrt{3}=3(\sqrt{5}+\sqrt{3}) \]
