#1 nope. you missed a minus sign
#2 could be right, if there was supposed to be a +5 in there
#3 nope
#4 nope
#5 nope. you added, but you should have subtracted. If I ask how much bigger 6 is than 2, you don't add 6+2.
#6 nope. you add exponents when multiplying powers. Your answer is (7^5)^6
#7 nope - same reason
#8 nope - subtract exponents when dividing powers
#9 nope - same reason
10 B
#11 nope
j^7 * j^1 = j*j*j*j*j*j*j * j
You can see why you add the exponents, not multiply them
#12 ok - makes me wonder why you missed the others

I cant really trust bruh because it can seem like bruh used different names but here when I see if there correct if there not I'll post the actual answers
(update) bruh is correct for the polynomial and properties of exponents practice! Safe to use bruhs answers
Tysm "bruh"
You're a lifesaver :p
