Solving Exponential Equations by Rewriting the Base

Question 24 • DHS Algebra 2 V

Solve: 493x = 3432x+1

Answer
A
x = –3
B
x = 1
C
x = 3
D
no solution

Explanation

Rewrite the bases as powers of 7: 49 = 7² and 343 = 7³. Then the equation becomes 7^(6x) = 7^(6x+3), which would require the exponents to be equal: 6x = 6x + 3. That is impossible, so the equation has no solution.
