Q. Simplify. Express your answer using positive exponents.(4j9)(7j)
Identify Components: Identify the components of the expression that can be combined.We have two terms, 4j9 and 7j, which can be multiplied together. We will group the coefficients (4 and 7) and the variables with exponents (j9 and j1, since j is the same as j1).
Multiply Coefficients: Multiply the coefficients.Multiply the numerical coefficients 4 and 7 together.4×7=28
Apply Product Rule: Apply the product rule for exponents.When multiplying powers with the same base, we add the exponents.j9×j1=j(9+1)=j10
Combine Results: Combine the results from Step 2 and Step 3.Now we can write the expression in its simplest form by combining the coefficient with the variable and its exponent.(4j9)(7j)=28j10
