Question 229584
 f(x)= 6434x to the -4/3 power. x=18
:
 {{{f(x)=6434x^(-4/3)}}}
:
{{{f(x)=6434*18^(-4/3)}}}
reciprocal gets rid of the negative exponent
f(x) = {{{6434/(18^(4/3))}}}
:
find 18^(4/3) on a calc
f(x) = {{{6434/47.1733}}}
:
f(x) = 136.39
;
:
You can check this on a calc; enter: 6434*18^(-4/3) = 136.39
