Question

Find x if 9^8 + 9^4 = 3^x+3

Answer 1

Answer:

Step-by-step explanation:

3^x+3=9^8+9^4

3^x+3-3=9^8+9^4-3

3^x=9^8+9^4-3

3^x=43053279

Answer 2

Here is your answer




(9)^8+(9)^4=(3)^x+(3)^1

=(3*3)^8+(3*3)^4=3^x+3^1
=(3^2)^8+(3^2)^4=3^x+3^1
So all 3 got common
Therefore
(2)8+(2)4=x+1
=16+8=x+1
=24-1=x

Answer =x is 23
