Q. Simplify. Assume all variables are positive.r49⋅r43r43Write your answer in the form A or BA, where A and B are constants or variable expressions that have no variables in common. All exponents in your answer should be positive.______
Identify Properties: Write down the expression and identify the properties to use.We have the expression r43/(r49∗r43). We will use the properties of exponents to simplify this expression.
Combine Exponents: Combine the exponents in the denominator using the product of powers property.The product of powers property states that am×an=am+n when the bases are the same. So, we combine the exponents in the denominator:r49×r43=r49+43=r412=r3.
Rewrite Expression: Rewrite the original expression with the simplified denominator.Now we have r43/r3.
Simplify Using Quotient of Powers: Simplify the expression using the quotient of powers property.The quotient of powers property states that am/an=am−n when the bases are the same. So, we subtract the exponents:r43/r3=r43−3=r43−412=r−49.
Make Exponent Positive: Since we want all exponents to be positive, we rewrite the expression with a positive exponent.To make the exponent positive, we take the reciprocal of the base:r(−9/4)=1/r(9/4).
