{{{(16g^-7h^8i^-21j^0k^9)(h^-5j^-6)^-12(7g^5h^11i^-1k^20)^3/(5g^-7h^14i^-30j^1k^9)(4h^1i^2j^-5k^-4)^(-4)}}}
= {{{(16g^-7h^8i^-21k^9)(h^60j^72)(343g^15h^33i^-3k^60)/(5g^-7h^14i^-30j^1k^9)((1/256)h^-4i^-8j^20k^16)}}}
= {{{(4096i^-24k^69)(h^101j^72)(343g^15)/(5h^10i^-38j^21k^25)}}}
= {{{(4096h^91i^-24k^69)(j^72)(343g^15)/(5i^-38j^21k^25)}}}
= {{{(4096h^91i^14k^44)(j^51)(343g^15)/(5)}}}
= {{{4096*343g^15h^91i^14k^44j^51/5}}}
