The reason is that you almost always want the negation to happen after the exponentiation, because it otherwise wouldn’t have any effect (at least when the exponent is even).
-27^2/3would come out to a different number, because the exponentiation has a higher precedence than the negationAh, so without parentheses, it would be:
x = -27^2
x / 3?
That doesn’t sound very intuitive though…
yup:
(-27)^2/3=((-27) ^ 2) / 3-27^2/3=(-(27 ^ 2)) / 3The reason is that you almost always want the negation to happen after the exponentiation, because it otherwise wouldn’t have any effect (at least when the exponent is even).
Thanks! 😃
