Question 132281
{{{(2x + 3)^3 - 64}}}
This can't be "solved" because it's not an equation
If the minus sign is supposed to be an equals sign,
Then,
{{{(2x + 3)^3 = 64}}}
{{{(2x + 3)^3 = 4^3}}}
{{{2x + 3 = 4}}}
{{{2x = 1}}}
{{{x = 1/2}}}
check:
{{{(2x + 3)^3 = 64}}}
{{{(2*(1/2) + 3)^3 = 64}}}
{{{(1 + 3)^3 = 64}}}
{{{64 = 64}}}
OK
