Q. Fully simplify using only positive exponents.18x2y845x2y8Answer:
Simplify Coefficients: First, we will simplify the coefficients (numerical parts) of the fraction by dividing 45 by 18.45÷18=2.5
Divisibility by 9: However, we realize that 45 and 18 are both divisible by 9, which is a more appropriate simplification for integers.45÷9=518÷9=2So, the simplified coefficient part is 25.
Simplify Variable Parts: Next, we will simplify the variable parts. Since the exponents of x and y are the same in the numerator and the denominator, we can divide them out.x2/x2=x2−2=x0=1 (since any number to the power of 0 is 1)y8/y8=y8−8=y0=1
Combine Coefficients and Variables: Now, we combine the simplified coefficient and variable parts. (25)×(1×1)=25
