#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
