Answer:
Step 2 because Richard multiply the powers of same base in denominator instead adding powers of same base.
Step-by-step explanation:
We are given that Richard simplified an expression in threes steps
We have to find the incorrect step in simplification of Richard
Step 1: all the exponent are multiplied by 3
Step 2:The exponents in the denominator are multiplied
Step 3:The exponents of the same base are subtracted during division
Richard makes mistake in step 2 when we multiply then power of same base should be added but Richard multiply the powers of same base in denominator.
I think we’re talking about the 15, the smallest number for 15 would be 3. Because 3 x 5 = 15
