Question

simplify the square root of 8 + the square root of 50

Answer 1

\[2\sqrt{2}+5\sqrt{2}=5\sqrt{2}\]

Answer 2

sqrt(8) = sqrt(4*2) = sqrt(4)*sqrt(2) = 2sqrt(2)
sqrt(50) = sqrt(25*2) = sqrt(25)*sqrt(2) = 5sqrt(2)
add like terms
2+5 = 7
=
7sqrt(2)

Answer 3

should be \[7\sqrt{2}\]
sorry

Answer 4

\[\sqrt{8}+\sqrt{50}=\sqrt{(2)(4)}+\sqrt{(2)(25)}
=\sqrt{2}\sqrt{4}+\sqrt{2}\sqrt{25}
=2\sqrt{2}+5\sqrt{2}=\sqrt{2}(2+5)=7\sqrt{2}\]
