Q. Simplify. Express your answer using positive exponents.2y4⋅y86y4
Write Expression, Identify Like Terms: Write down the given expression and identify like terms.The given expression is 2y4⋅y86y4. We can see that y4 appears in both the numerator and the denominator, and we will need to simplify these terms.
Simplify Coefficients and Powers: Simplify the coefficients and the powers of y separately.First, we simplify the coefficients. We have 6 in the numerator and 2 in the denominator, which can be simplified as 26.26=3Next, we simplify the powers of y. We have y4 in the numerator and y4×y8 in the denominator. When dividing powers with the same base, we subtract the exponents.y4×y8y4=y4+8y4=y12y4
Apply Laws of Exponents: Apply the laws of exponents to simplify the powers of y. Using the law of exponents for division, we subtract the exponents of y. y12y4=y(4−12)=y−8 Since we want to express the answer using positive exponents, we can write y−8 as y81.
Combine Coefficients and Powers: Combine the simplified coefficients and powers of y. We have the coefficient 3 from step 2 and the power of y as y81 from step 3. Combining these gives us the final simplified expression. 3×(y81)=y83
