Answer :

Given,

3⁴ × 3⁵ = (3³)ˣ

⇒ 3⁴⁺⁵ = (3³)ˣ

⇒ 3⁹ = (3³)ˣ

⇒ (3³)³ = (3³)ˣ

Comparing both sides, we get x = 3

∴ The required value of x is 3

Answer:

The value of x is 3

Step-by-step explanation:

Given 3^{4}\times 3^{5}=(3^{3})^{x}

Using the rule of indices,

  • bases are same, powers can be added. a^{x}\times a^{y}=a^{x+y}
  • power raised to a power, then powers are multiplied together.(a^{x})^{y}=(a)^{xy}

the given equation can be written as

3^{4}\times 3^{5}=(3^{3})^{x}\implies 3^{4+5}=3^{3x}

\implies 3^{9}=3^{3x}

When bases are equal, powers are also equal, a^{x}= a^{y} \implies x=y

Therefore, equating the powers, 3x=9

\implies x=\frac{9}{3} =3

Hence, the value of x is 3.
