\[\frac{ -2a^3b^{-2}a^4 }{ -a^4b^{-2} }\implies \frac{ -2a^7b^{-2} }{ a^4b^{-2} }\implies -2a^{11}\]

almost, just two small mistakes
Vocaloid
  • Vocaloid
first mistake is the denominator (-a^2*b^-1)^2 = a^2*b^-4 the negative sign cancels out, since (-1)^2 = 1
Vocaloid
  • Vocaloid
second mistake is a^7/a^4 = a^3, not a^11 (subtract the exponents)

@Vocaloid So would 2a^3 be correct?
Vocaloid
  • Vocaloid
almost, -2a^3
calculusxy
  • calculusxy
yeah sorry about that.. it was a typo so -2a^3 is correct right?
Vocaloid
  • Vocaloid
