Ben simplified this expression. 1. 2. Analyze Ben’s work. Did he simplify the expression correctly? If not, what was his mistake
? Yes, he is correct. No, he needed to add the exponents of powers of the same base in the first step. No, he needed to apply the exponent to all factors in the product in the second step. No, he needed to simplify further by subtracting the exponents of the powers.
X= 12 Add three on both sides to get rid of it 9+3 and -3 + 3 the three is negative because you drop the minus sign down This cancels out the three and 9+3 is 12 so X=12
