Q. Fully simplify using only positive exponents.10x7y830xy8Answer:
Simplify Coefficients: Simplify the coefficients.Divide the coefficients 30 by 10 to simplify the expression.1030=3
Simplify x Terms: Simplify the x terms.Divide x by x7 to simplify the x terms. Since x is the same as x1, we use the property of exponents that states xa/xb=xa−b.x/x7=x1−7=x−6However, we want only positive exponents, so we will keep this in mind for the final answer.
Simplify y Terms: Simplify the y terms.Divide y8 by y8 to simplify the y terms. Using the property of exponents that states ya/yb=ya−b when a=b, the y terms cancel out.y8/y8=y8−8=y0=1
Combine Terms: Combine the simplified terms.Combine the simplified coefficients and variables. Since we want only positive exponents, we will express x−6 as x61.Final simplified expression: 3×1×x61=x63
