Question

plzzz give me explanatio​

Answer 1

Answer:

i) 5^(2x+3)=1

a^0=1

therefore,

2x+3=0

2x=-3

x=-3/2

ii)(√(3/5))^x+1=125/27

√a=a^½

((3/5)^½)^x+1= (5/3)³

1/a=a^-1

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

x+1 = -3

2

x+1=-6

x=-6-1

x=-7

Answer 2

Answer:

It is given that,

1)5^2x+3=1

We know that,a°=1

5^2x+3=5°

When bases are equal, then it's powers also equal..

2x+3=0

X=-3/2

2)(3/5)^x+1/2=5³/3³

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

X+1/2=-3

X+1=-6

X=-7

Step-by-step explanation:

Hope it helps you.......
