Question

Need help with expressing this.

Please use step by step.

Thank you.

Answer 1

`\frac{ {2b}^(2) }{5a ^(4) }`

Explanation:

Move a^-4 to the denominator using the negative exponent rule b^-n = 1/b^n.

`(2)/(5b^( - 2)a^(4) )`

Move b^-2 to the numerator using the negative exponent rule 1/b^-n = b^n.

`\frac{ {2b}^(2) }{ {5a}^(4) }`

Hence, if we express this equation with positive exponents, we'll get the answer 2b^2/5a^4.
