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
