Question

Tolong jawab semua kalo bisa, tak kasih poin banyak

Answer 1

1. (1/16)^(x-1)=32
2^(-4(x-1))=2^5
2^(-4x+4)=2^5
-4x+4=5
-4x=1
x=-¼

2. (1/25)^(x-2)=5^(x+1)
5^(-2(x-2))=5^(x+1)
-2x+4=x+1
-3x=-3
x=1

3. ³√(25^(x+4))=125^(x+1)
5^(⅔(x+4))=5^(3(x+1))
⅔x+(4/3)=3x+3
2x+4=9x+9
-7x=5
x=-5/7

4. 3².3^(2x+5)=1
3^(2+2x+5)=3^0
2+2x+5=0
2x=-7
x=-7/2
