Answer:

x = [tex]\frac{5}{7}[/tex]

Step-by-step explanation:

We can start simplifying this equation by expanding the parenthesis and cross multiplying.

[tex](7^x)^4 = \frac{7^2 * 7^3}{7^{3x}} = \\\\\\7^{4x} = \frac{7^5}{7^{3x}}\\\\\\7^5 = 7^{7x}\\\\\\[/tex]

The exponent 5 and 7x are equal:

[tex]\longmapsto[/tex]Divide both sides by 7

[tex]5 = 7x\\\\x = \frac57[/tex]

Answer:

  • 5/7

Step-by-step explanation:

Use identities:

  • [tex](a^b)^c = a^{bc}\\a^ba^c=a^{b+c}\\a^b/a^c=a^{b-c}\\a^b=a^c -->b = c[/tex]

Solve as below:

  • (7ˣ)⁴ = 7² · 7³ / 7³ˣ
  • 7⁴ˣ = 7⁵ / 7³ˣ
  • 7⁴ˣ = 7⁵ ⁻ ³ˣ
  • 4x = 5 - 3x
  • 4x + 3x = 5
  • 7x = 5
  • x = 5/7
