Q. Express the following fraction in simplest form, only using positive exponents.(3p2)5−5p−5Answer:
Write Expression: Write down the given expression.We have the expression (−5p−5)/((3p2)5).
Simplify Denominator: Simplify the denominator.The denominator is (3p2)5. According to the power of a power rule, we multiply the exponents.(3p2)5=35×(p2)5=35×p2×5=35×p10.
Rewrite Expression: Rewrite the expression with the simplified denominator.Now the expression is (−5p−5)/(35⋅p10).
Deal with Negative Exponent: Simplify the expression by dealing with the negative exponent in the numerator. A negative exponent means that the base is on the wrong side of the fraction line, so we move it to the denominator to make the exponent positive. 35⋅p10−5⋅p5.
Calculate Value: Calculate the value of 35. 35=3×3×3×3×3=243.
Combine Terms: Combine the terms in the denominator.Now we have (−5)/(243⋅p10)⋅p5.
Combine p Terms: Simplify the expression by combining the p terms.We subtract the exponents of p because we are dividing powers with the same base.(−5)/(243⋅p10−5)=(−5)/(243⋅p5).
Write Final Expression: Write the final simplified expression.The final simplified expression is (−5)/(243⋅p5).
