Sum

Solution
Given: `3^(5x - 1) = root(4)(3)`
Step-wise calculation:
1. Express the fourth root of 3 as an exponent:
`root(4)(3) = 3^(1/4)`
2. Set the exponents equal since the bases are the same (3):
`5x - 1 = 1/4`
3. Solve for (x):
`5x = 1 + 1/4`
`5x = 4/4 + 1/4`
`5x = 5/4`
`x = 5/4 ÷ 5`
`x = 5/4 xx 1/5`
`x = 1/4`
