Jawabannya sudah ada jadi tolong tuliskan caranya ya...

Answer 1

33) (5³)² + (5⁴)²
= 5^³'² + 5^⁴'²
= 5^6 + 5^8
= 5^6(1 + 5²) (A)

34) (4√8 - 3√2) √32 + √72
= (8√2 - 3√2) 4√2 + 6√2
=( 5√2 × 4√2) + 6√2
= 40 + 6√2 (D)

35) L = ½ . 3√6 . 8√3
= ½ . 24√18
= ½ . 72√2
= 36√2 (B)

36) (3/5)⁴ = (5/3)^x
(5/3)^x = 1 / (5/3)⁴
jadi (5/3)^x = (5/3)-⁴
~ x = -4 (C)

37) L = s²
= 16²
= 256 cm² (C)

38) (2 - √2) / (√3 - √2)
= {(2-√2)/(√3-√2)} × {(√3+√2)/(√3+√2)}
= {(2-√2)((√3+√2)} / {(√3-√2)(√3+√2)}
= (2√3 - √6 + 2√2 - 2)
---------------------------
3 - √6 + √6 - 2
= (2√3 - √6 + 2√2 - 2) / 1
= 2√3 - √6 + 2√2 - 2 (D)

39) √8 + √27 + √75
= 2√2 + 3√3 + 5√3
= 2√2 + 8√3
= 2b + 8a
= 8a + 2b (D)

40) (2√96 × √108) / 6√12
= 8√6 × 6√3
---------------
12√3
=8√6
-------
2√3
= {(8√6)(2√3)}/ {(2√3)(2√3)}
= 16√18
------------
12
= 48√3
----------
12
= 4√3 (tdk ada opsi)
