See a solution process below:

Explanation:

First, use this rule for exponents to rewrite the 5 term.

a = a^color(red)(1)

(5x^6y^4)^2 => (5^color(red)(1)x^6y^4)^2

Now, use this rule for exponents to eliminate the outer exponent:

(x^color(red)(a))^color(blue)(b) = x^(color(red)(a) xx color(blue)(b))

(5^color(red)(1)x^color(red)(6)y^color(red)(4))^color(blue)(2) => 5^(color(red)(1)xxcolor(blue)(2))x^(color(red)(6)xxcolor(blue)(2))y^(color(red)(4)xxcolor(blue)(2)) => 5^2x^12y^8 => 25x^12y^8
