Q. Fully simplify using only positive exponents.\newline45x2y818x2y8 \frac{45 x^{2} y^{8}}{18 x^{2} y^{8}} \newlineAnswer:
  1. Simplify Coefficients: First, we will simplify the coefficients (numerical parts) of the fraction by dividing 4545 by 1818.\newline45÷18=2.545 \div 18 = 2.5
  2. Divisibility by 99: However, we realize that 4545 and 1818 are both divisible by 99, which is a more appropriate simplification for integers.\newline45÷9=545 \div 9 = 5\newline18÷9=218 \div 9 = 2\newlineSo, the simplified coefficient part is 52\frac{5}{2}.
  3. Simplify Variable Parts: Next, we will simplify the variable parts. Since the exponents of xx and yy are the same in the numerator and the denominator, we can divide them out.\newlinex2/x2=x22=x0=1x^{2}/x^{2} = x^{2-2} = x^0 = 1 (since any number to the power of 00 is 11)\newliney8/y8=y88=y0=1y^{8}/y^{8} = y^{8-8} = y^0 = 1
  4. Combine Coefficients and Variables: Now, we combine the simplified coefficient and variable parts. (52)×(1×1)=52(\frac{5}{2}) \times (1 \times 1) = \frac{5}{2}
