So I think that number 6 is just dividing by 3 and the second one doesn't like divide so number 7 is no and number 6 is yes
Could you zoom out a little maybe? it looks like you cut off something in front of dot
Y = sallys grocerys
x = how much sally paid
y - (.05) = x
You would multiply the power by the powers of both exponents
2 × 3 = 6 so a^6
3 × 4 = 12 so b^12
Answer is
a^6b^12
