PLZ HELP! Rocky simplified an expression in three steps, as shown: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:
Step 3 is wrong because when dividing exponents you subtract them x^-10 would be multiplying by x^-12 making it x^-10-12 and that would be x^-22 same applies for the y exponents
