Question

Quick anyone know the answer to this algebra question?

Answer 1

Answer:
`\bold{b)\ (-3\cdot a^7\cdot b^3\cdot b^1)/(15\cdot a^2) }`

Explanation:

Move the term that has a negative exponent to the other side of the fraction bar. This changes the negative exponent to a positive exponent.

`(-3\cdot a^(-2)\cdot b^3)/(15\cdot a^(-7)\cdot b^(-1))\\\\\\\text{move }a^(-2)\text{ to the bottom and }a^(-7)\text{ to the top. Change the sign of the exponent.}\\\\(-3\cdot a^7\cdot b^3)/(15\cdot a^2\cdot b^(-1))\\\\\\\text{move }b^(-1)\text{ to the top. Change the sign of the exponent.}\\\\(-3\cdot a^7\cdot b^3\cdot b^1)/(15\cdot a^2)`
