Explanation Given: The expression ( y 2 z − 4 y − 3 z 4 ) − 2 . Definition used: Negative exponents : If a is any nonzero real number and n is a positive integer, then a − n = 1 a n . Property used: 1. For any real number a , a m ⋅ a n = a m + n , where m and n are any integers. 2. For any real number a , a m a n = a m − n , where m and n are any integers. 3. For any real number a , ( a m ) n = a m n , where m and n are any integers. 4. For any real numbers a and b , ( a b ) m = a m b m , where m and n are any integers. Calculation: Apply property 4 with a = y 2 z − 4 , b = y − 3 z 4 , and m = − 2 , ( y 2 z − 4 y − 3 z 4 ) − 2 = ( y 2 z − 4 ) − 2 ( y − 3 z 4 ) − 2 Apply property 3 and simplify the terms
