pentagon [3]3 years ago
4 0

Answer:

  • x = - 2.5

Step-by-step explanation:

  • 3^{4x - 5}=(1/27)^{2x + 10}
  • 3^{4x - 5}=(1/3^3)^{2x + 10}
  • 3^{4x - 5}=(3^{-3})^{2x + 10}
  • 3^{4x - 5}=3^{-3*(2x + 10)}
  • 4x - 5 = - 3*(2x + 10)
  • 4x - 5 = - 6x - 30
  • 4x + 6x = 5 - 30
  • 10x = - 25
  • x = - 2.5

Positive exponent? An index would imply that the base, x, had a fractional exponent.

My Dear Aunt Sally used to say, "If there's a negative exponent in your face, then flip your base!"

In other words, if the exponent is negative, take the reciprocal of the base, x → \frac{1}{x} and change the exponent to positive.

Therefore:   x^{-3} = \frac{1}{x^3}

I have cross the fraction bar line change the exponent sign.
