Final answer:
To simplify the expression m7 m-4⋅m3/m3-m11 . 1/m28, combine the exponents and use the properties of exponents. The simplified expression is m14.
Step-by-step explanation:
To simplify the expression m7 m-4 · m3/m3-m11 · 1/m28, we can combine the exponents and use the properties of exponents. Combining the exponents in the numerator, we have m(7-4+3) = m6. In the denominator, we have m(3-11) = m-8. Combine the exponent in the denominator, we get m6/m-8. Using the rule for dividing exponents (ma/mb = ma-b), we have m6-(-8) = m6+8 = m14.
