Answer 1

Answer:

x to the 12 over 35

Step-by-step explanation:

Given expression,

Open parentheses x to the 4 fifths power close parentheses,

$\implies (x^\frac{4}{5})^\frac{3}{7}$

By using the property of exponent $(a^m)^n=a^{mn}$

We get,

$=x^{\frac{4}{5}\times \frac{3}{7}}$

$=x^\frac{12}{35}$

= x to the 12 over 35,

Second option is correct.
