Help with <span title="integers!!!!!!!!!!!!!!!!!!!?">integers!!!!!!!!!!!!!!!!!...</span>

Question

All in all, i get integers, but today we got into an aspect that I don't get. For example..........-5(squared)(-3), shouldnt this equal -75 since -5 squared is a positive number and -3 is a negative number and therefore the answer is negative? However in my textbook it says that the answer is 75. PLEASE HELP....EXPLAIN!!!!!!!!!!!!!!!!!!

Thanks in advance!!!!!!!!!!!!!!!!!!!!!!

Answer 1

if this is what the question reads:

(-5)^2(-3)

then u are correct and the answer will be negative since (-5)^2 is positive and then is multiplied by a (-).  

Answer 2

i think so too but when i typed &quot;-5(squared) in to the Ti-30X2S (calculator) it says the answer is 25.

Answer 3

textbook wrong !!!??!!!!

Answer 4

(-5)²(-3)=(25)(-3)=-75

(-5²)(-3)=(-25)(-3)=75

It all depends on how it is written. If it is written as (-5)² this means the (-5)(-5) which is 25 but if it&#039;s written as -5² this means -(5)(5)=-25
