Q. Simplify. Express your answer using positive exponents. u⋅4u4u6
Write & Simplify Expression: Write down the expression and simplify the coefficients and variables separately. u×4u4u6 can be rewritten as 4u24u6 since u×4u is the same as 4u2.
Simplify Coefficients: Simplify the coefficients.The coefficient 4 in the numerator and denominator cancels out because 44 equals 1.So, 4u24u6 becomes u2u6.
Apply Quotient Rule: Apply the quotient rule for exponents.When dividing powers with the same base, subtract the exponents: u6/u2=u(6−2)=u4.
Write Final Expression: Write the final simplified expression.The expression u⋅4u4u6 simplifies to u4.
