Question

3 to Power x+1=27.3to the power 4

Answer 1

According to question

3^x+1 = 27×3 ^4

3^x+1 = 3^8

or x+1 = 8(using identity a^m=a^n)

or x=8-1

hence,x = 7

Answer 2

Answer:

x=7

Step-by-step explanation:

3^x+1=27 . 3^4

when bases are equal equate the powers

x+1=3+4

x+1=7

shift 1 on left side

x=7-1

x=6

correct or wrong

x=6

3^6+1=3^3 . 3^4

3^7=3^3 . 3^4

Hence proved

.

. . x=6 is correct answer
