tolong bantu kak beserta caranya ya..
28) √54 : √3 = √18 = √9 x √2 = D. 3 √2
29) = 4 x 4 : 2 = 16 : 2 = D. 8
30) √6x1/4 = √25/4 = C. 5/2
31) = (2 1/4)^2 = (9/4)^2 = 81/16 = B. 5 1/16 [answer.2.content]
Jawab:
[27] A. = 5√2
[28] D. = 3√2
[29] D. = 8
[30] C. = ⁵/₂
[31.] B. = 5 ¹/₆
Penjelasan dengan langkah-langkah:
[27] √300 ÷ √6 = √(300÷6) = √50 = √(25·2) = √25√2 = 5√2 (A.)
[28] √54 ÷ √3 = √(54÷3) = √18 = √(9·2) = √9√2 = 3√2 (D.)
[29] ³√64 × √16 ÷ ⁵√32 = 4 × 4 ÷ 2 = 16 ÷ 2 = 8 (D.)
[30] √(6¼) = √(6+¼) = √(²⁴/₄+¼) = √(²⁵/₄) = √25 ÷ √4 = ⁵/₂ (C.)
[31.] ³√(2¼)⁶ = [tex](2\:^1/_4)^{6\div3}[/tex] = (2¼)² = (2+¼)² = (⁸/₄+¼)² = (⁹/₄)² = ⁸¹/₁₆ = ⁸⁰/₁₆+¹/₆ = 5+¹/₆ = 5 ¹/₆ (B.)
