Question

How do you divide `\frac { x ^ { - 7} ( y ^ { - 4} z ^ { 1} ) ^ { 2} } { x ^ { - 6} y ^ { 5} z ^ { 8} }`?

Answer 1

`frac\{1}{xy^13z^6}`

Explanation:

Reduce the fraction with `x^-7`
`frac\{(y^-4z)^2}{xy^5z^8}`
Use exponent rules. To raise a product to a power, raise each factor to that power.
`frac\{y^-8z^2}{xy^5z^8}`
Reduce the fraction
`frac\{1}{xy^13z^6}`
