Solve the Inequality for x 1/(16^(3x-4))<=64^(x-1)

$\frac{1}{16^{3 x - 4}} \leq 64^{x - 1}$

Move $16^{3 x - 4}$ to the numerator using the negative exponent rule $\frac{1}{b^{- n}} = b^{n}$ .

$16^{- (3 x - 4)} \leq 64^{x - 1}$

Create equivalent expressions in the equation that all have equal bases.

$4^{2 (- (3 x - 4))} \leq 4^{3 (x - 1)}$

Since the bases are the same, then two expressions are only equal if the exponents are also equal.
