Answer:
x = 6.0139
Step-by-step explanation:
1) think of the first side of the equation as: 6^(8/2) - simplify by dividing the 8 by 2 to get 6^4.
2) The Equation now is 6^4 = 216x - 3, turn 6^4 into 1296 and add 3 to both sides to get 1299 = 216x.
3)Divide both sides by 216 to get x = 6.0139 (which is approximately close to 6 but technically plugging the answer into the equation in step 2 would yield 1296 = 1296).
