Q:

Rocky simplified an expression in three steps, as shown:x to the power of negative 5 multiplied by y to the power of 2, over y multiplied by x to the power of 3 multiplied by x to the power of 3 multiplied by y to the power of negative 5, the whole to the power of 2 equals x to the power of negative 10 multiplied by y to the power of 4, over y to the power of 2 multiplied by x to the power of 6 multiplied by x to the power of 6 multiplied by y to the power of negative 10 equals x to the power of negative 10 multiplied by y to the power of 4, over y to the power of negative 8 multiplied by x to the power of 12.Which is the first incorrect step and why? Step 1, all the exponents are increased by 2 Step 1, all the exponents are multiplied by 2 Step 2, the exponents in the denominator are added during multiplication Step 3, the exponents of the same base are added during division

Accepted Solution

A:
Answer:Step three is wrong because when you divide use the quotient rule which is in division the exponents are subtracted and in this problem the exponents are added
