Question 75253
#1
{{{(- 64/26) ^ (1/3)}}}
{{{(-64)^(1/3)/(26) ^(1/3)}}} Distribute the exponent
{{{(-4)/(26) ^(1/3)}}} Simplify
The expression could also look like:
{{{(-4)/(root (3,26))}}}




#2
{{{(27/64) ^ (-4/3)}}}
{{{(27)^(-4/3)/(64) ^(-4/3)}}} Distribute the exponent
{{{(3)^(-4)/(4) ^(-4)}}} take the cube root
{{{(4)^(4)/(3) ^(4)}}} invert the bases with negative exponents
{{{256/81}}} Theres the simplified form.
