  • Answer:

    Option 3rd is correct.

    [tex]b^{20}[/tex]

    Step-by-step explanation:

    Using the exponent rules:

    [tex](a^n)^m = a^{nm}[/tex]

    Given the expression:

    [tex](b^5)^4[/tex]

    Apply the exponent rules, we have;

    [tex]b^{5 \cdot 4} = b^{20}[/tex]

    Therefore, the correct simplification of the given expression is, [tex]b^{20}[/tex]
