Answer:
[tex] \frac{ {2b}^{2} }{5a ^{4} } [/tex]
Step-by-step explanation:
Move a^-4 to the denominator using the negative exponent rule b^-n = 1/b^n.
[tex] \frac{2}{5b^{ - 2}a^{4} } [/tex]
Move b^-2 to the numerator using the negative exponent rule 1/b^-n = b^n.
[tex] \frac{ {2b}^{2} }{ {5a}^{4} } [/tex]
Hence, if we express this equation with positive exponents, we'll get the answer 2b^2/5a^4.
