Solution steps

\frac{7}{7 ^{3}}

Apply exponent rule:

\frac{x ^{a}}{x ^{b}} = \frac{1}{x ^{b - a}}

= \frac{1}{7 ^{3 - 1}}

Subtract the numbers:

3 - 1 = 2

= \frac{1}{7 ^{2}}

7^{2} = 49

= \frac{1}{49}

53700000 x^{2} - 2097640 x + 2319.84 = 0

lo g_{4} (0.6)

\frac{1}{3} x^{2} + \frac{8}{3} x + \frac{13}{3} = - \frac{1}{3} x^{2} - \frac{2}{3} x + \frac{5}{3}

- \frac{7}{2} (\frac{1}{100}) + \frac{7}{2}

\frac{1}{∣ x - 3 ∣} > 0
