Question

Find the value of n if: 8 × 2^n+2 = 32
Pls write steps and then send

Answer 1

8*2^n+2=32

2^n+2=32/8

2^n+2=4...                         4 can be written as 2^2

therefore,

            2^n+2=2^2

            n+2=2

                n=0 is the answer....

Answer 2

8 × 2^n + 2 = 32

8 × 2^n = 30

2^n = 15 / 4

log ( 2^n ) = log ( 15 / 4 )

n log ( 2 ) = log ( 15 / 4 )

n log ( 15/4 ) / log 2

n = log 2 ( 15 / 4 )
