Q. Simplify the following expression to simplest form using only positive exponents.(32x10y5)−51Answer:
Understand Problem: Understand the problem and apply the negative exponent rule.The negative exponent rule states that a−n=an1. We will apply this rule to the entire expression.
Apply Negative Exponent Rule: Apply the negative exponent rule to the expression.(32x10y5)−(1)/(5)=(32x10y5)1/51
Simplify Expression Inside Parentheses: Simplify the expression inside the parentheses by taking the fifth root.The fifth root of 32 is 2, because 25=32.The fifth root of x10 is x10/5=x2, because (x2)5=x2⋅5=x10.The fifth root of y5 is y5/5=y1=y, because y1=y.(32x10y5)1/51=2x2y1
Write Final Simplified Expression: Write the final simplified expression with only positive exponents.The final expression is 2x2y1.
