Question 252903
{{{5sqrt(49)}}}
the {{{sqrt(49)}}} = 7, so
we get 5x7 = 35.
--
{{{sqrt(-27)^3}}}
{{{(-27)^3 = ((-3)^3)^3 = (-3)^9}}}
So,
{{{sqrt((-3)^9)}}}.
I don't know what you know about negative square roots: We have one of two answers:
(i) no solution.
{{{sqrt((3)^9) * sqrt((-1)^9)}}}
81sqrt(3) x i
(ii) 80isqrt(3)
