write the following as SINGLE POWERS (if possible) using exponent laws (-4) x (-4) /\ 9
(22x22)^9
(-4) x (-4) /\ 9=-(2^2) x -(2^2)^9=-(2^2) x -(2^18)=2^20
Alan: Isn't the 2nd [(-4)^9 only] X (-4) =2^20. It is NOT [(-4) X (-4)]^9=2^36
You are right! Exponentiation takes precedence over multiplication. I must be half asleep!
