Q. Fully simplify using only positive exponents.125x3y45x4y2Answer:
Simplify coefficients: Simplify the coefficients.The coefficient 5 can be divided by 125 to simplify the fraction.(1255)=251
Simplify x terms: Simplify the x terms using the quotient rule for exponents.The quotient rule states that am/an=a(m−n) when a is not equal to 0.x4/x3=x(4−3)=x1=x
Simplify y terms: Simplify the y terms using the quotient rule for exponents.y4y2=y(2−4)=y−2
Rewrite with positive exponents: Rewrite the expression with only positive exponents.Since we cannot have negative exponents in the final answer, we move y−2 to the denominator to make the exponent positive.(251)x(y−2)=(251)x/(y2)
Combine simplified parts: Combine all the simplified parts to write the final answer. (251)x/(y2)
