Bntu jwbnbb dong kakak abg plsss

Jawaban:

2 (2 sqrt(2) – 3) (B)

Penjelasan dengan langkah-langkah:

Simplify the following:

sqrt(8) + sqrt(50) – sqrt(36) – sqrt(18)

sqrt(36) = sqrt(6^2) = 6:

sqrt(8) + sqrt(50) – 6 – sqrt(18)

sqrt(18) = sqrt(2×3^2) = 3 sqrt(2):

sqrt(8) + sqrt(50) – 6 – 3 sqrt(2)

sqrt(8) = sqrt(2^3) = 2 sqrt(2):

2 sqrt(2) + sqrt(50) – 6 – 3 sqrt(2)

sqrt(50) = sqrt(2×5^2) = 5 sqrt(2):

2 sqrt(2) + 5 sqrt(2) – 6 – 3 sqrt(2)

Add like terms. 2 sqrt(2) + 5 sqrt(2) – 6 – 3 sqrt(2) = 4 sqrt(2) – 6:

4 sqrt(2) – 6

Factor 2 out of 4 sqrt(2) – 6 giving 2 (2 sqrt(2) – 3)
