Question

tolong kerjain yang b dan c sama nomer 7 a dan b
makasihh yaa tolong janga lebih dari jam 1 soalnya dikumpulin

Answer 1

N^5 = (32/243)
n^5 = (2^5) / (3^5)
n^5 = (⅔)^5
n = ⅔

[(5/9)^7 : (5/9)²]^n = (5/9)^15
(5/9)^7n : (5/9)^2n = (5/9)^15
(5/9)^7n-2n = (5/9)^15
5n = 15
n = 3

√(9/16) + 0,5²
= 3/4 + 1/4
= 4/4
= 1

√(169/256) + √(49/64)
= 13/16 + 7/8
= 13/16 + 14/16
= 27/16

Answer 2

7a.√9/16+(0,5)²
    =3/4+0,25
   =0,75+0,25
   =1
 7b.√169/256+√49/64
    =13/16+7/8
    =13/16+14/16
    =27/16
    =1 11/16
