2. x^-9/8 . y^-5/3
b. a^8/5 - b^2/3

3. ~ a = 1/(2³)-2/3
       a = 1/2^-2
       a = 4

~ b = (3²)3/2
   b = 27

a. 4a+3b - √4b²-20ab+25a²
= 4(4)+3(27) - √4(27)²-20(4)(27)+25(4)²
= 16+81 - √2916-2160+400
= 97 - √1156
= 97 - 34
= 63

b. (4)²+(27)²/(4)(27) - (4)+(27)/(4)(27)
= 16+729/108 - 31/108
= 745/108 - 31/108
= 714/108
= 6.61

4. a. 3^4x+1 = 3³^(x+5)
       3^4x+1 = 3^3x+15
4x+1 = 3x+15
4x-3x = 15-1
x = 14

4b sama 5a&b isi sendiri yah :)


tu no 2 bagian a dan b nya yg mna y ;)
