Question
488,489,490
Here is the transcription of the mathematical expressions from the image. These expressions can be useful for understanding polynomial equations, simplifying expressions, and other algebraic operations. 488. \((5a^2 + 2a - 12)(9a^2 + 8a - 4)\) 489. \((10x^2 - 3x + 5) - (4x^2 - 6)\) 490. \(\left(-\frac{3}{4}\right)^3\) 491. \(x^{-3} x^4\) 492. \(\frac{5^6}{5^8}\) 493. \((47a^{18}b^{23}c^5)^0\) 494. \(4^{-1}\) 495. \((2y)^{-3}\) No graphs or diagrams are present in the image. The list consists of various algebraic expressions involving polynomials, exponents, and variables.
