would it be negative?
replace x with 9 and see what happens x^3 = -27 9^3 = -27 729 = -27 .. this equation is false so x = 9 is not the answer
oh
note: 9^3 = 9*9*9
NOT 9^3 = 9*3

no that 3 is supposed to be the tiny number in the corner
yeah \(\LARGE x^3\) right?
yea
that means x cubed
when you cube a number, you have it multiplied 3 times by itself

7^3 = 7*7*7 8^3 = 8*8*8 etc etc
\(\large x ^{\color{red}{ 3}} = -27\implies \sqrt[{\color{red}{ 3}}]{x ^{\color{red}{ 3}}}=\sqrt[{\color{red}{ 3}}]{-27}\implies x=?\)
i dont no anything about square roots
oh i got the answer never mind @jdoe0001
