Question

2 power x + 1 is equal to 1

Answer 1

2^(x+1) = 1

Multiply by 2 on both sides

2*2^(x+1) = 1*2

2¹*2^(x+1) =2

If bases are same and in multiplication, powers are added

2^(1+x+1) =2¹

2^(x+2) = 2¹

x +2 =1

x =1-2

x= -1


By other method,

2^(x+1) = 1

2^(x+1) =2^(0)

x+1=0

x= -1

I hope this will help you
