Q. Fully simplify using only positive exponents.8x3y74x6y6Answer:
Factor out common terms: Write down the expression and factor out common terms.We have the expression (4x6y6)/(8x3y7). We can simplify this by factoring out common terms in the numerator and the denominator.
Divide coefficients: Divide the coefficients.Divide the numerical coefficients 4 by 8.84=21
Simplify x terms: Simplify the x terms.Divide the x terms using the rule xa/xb=x(a−b).x6/x3=x(6−3)=x3
Simplify y terms: Simplify the y terms.Divide the y terms using the rule ya/yb=y(a−b).y6/y7=y(6−7)=y−1Since we want only positive exponents, we can write y−1 as 1/y.
Combine simplified terms: Combine the simplified terms.Combine the simplified coefficients and variables.(21)×x3×(y1)=2yx3
