Answer:
[tex](-10a^{4b+4b^{3}})[/tex]
Step-by-step explanation:
Given in the question the expression,
[tex](-2a^{4b} )(5a^{4b^{3}})[/tex]
Step1
Product Rule
The exponent "product rule" tells us that, when multiplying two powers that have the same base, you can add the exponents.
so,
[tex](-2a^{4b})(5a^{4b^{3} })=(-10a^{4b+4b^{3}})[/tex]
