Question

Tolong jawab ini yah?
Pake cara juga :)
1-5 gak papa :)

Answer 1

1. 64^2/3 = (4^3)^2/3 = 4² = 16

2. (27/8)^2/3 = (3^3/2^3)^2/3 = (3/2)² = 9/4 (D)

3. 3^-2 + 4^-1 - 2^-3 = 1/3² + 1/4 - 1/2^3 = 1/9 + 1/4 - 1/8 = 8/72 + 18/72 - 9/72 = 17/72 (C)

4. 2√18 - √50 + √72 = 2√9.2 - √25.2 + √36.2 = 2.3√2 - 5√2 + 6√2 = 6√2 - 5√2 + 6√2 = 7√2 (A)

5. 3√7.√14 = 3√7.14 = 3√98 = 3√49.2 = 3.7√2 = 21√2 (D)
