tolong dong ini .........

JAWABANNYA:

59. a^-1×b^-3/a^-3×b^4
= a^(-1-3)b^(-3+4)
= a^2b1
= a^2b ------- A

60. ab^-2-a^-1/1+ba^-1
= ab^(-2-1)/1+1.ba
= ab^-1/2 ba
= a-b/ba^2 ------- D

61. a^-1.a^-2-6a^-3/a^-2+3a^-3
= a^(1-2+3)-6a^-3/3a^-3
= a^(-1)-6a^-3/3a^-3
= a^-1 - 2a
a = 2-(-1)
a = 3
a + 3 ---------- A

62. 9a^-1 - a/ 1+3a^-1
= 10a^-1/4a^-1
= 4a^-1=10^-1
a = 10^-1+4^-1
a = 14^-1-1
a = 14^-2
a= 14/-2
a= -7 ------ D

63. 5^-2 + 10^-2
= 0,05 + 0,10
= 0,15 ----- A

64. 1/8. 1/32
= 4-1/32
= 3/32 ----- C

65. 0,0001= 10^y
10^y= 0,0001
10^y= 10^-4
10^y= -4 ------ A
