Answer 1

10)
( (4a²b³)/(6ab^5) )-¹
= ( (6ab^5)/(4a²b³) )¹
= 6/4 x b^(5-3)/(a²-¹)
= 3b²/2a

2)
(-4)^5 x 8^-2/16-³
= -2^10 x 2^-6/2^-12
= 2^(10+12-6)
= 2^16

13)
2^(3x+5) = 1/16
2^(3x+5) = 2^-4
3x + 5 = -4
3x = -4-5 = -9
x = -9/3
x = -3

16)
(8x10^9 + 4x10^7)/(2x10⁴)
= (8.000.000.000 + 40.000.000)/(20.000)
= 8.040.000.000/20.000
= 804.000/2
= 402.000
= 4,02 x 10^5

19)
³√343 x ⁴√625 - 6√729 x √49
= 7 x 5 - 3 x 7
= 7 x (5-3)
= 7 x 2
= 14
