Question 180663
You really should use parentheses to clearly describe the problem!
Is it: {{{sqrt(80(a^4)b/5b)}}} or {{{sqrt((80a^(4b))/5b)}}} or {{{sqrt(80(a^4)b)/5b}}}
Evaluate:
{{{sqrt(80(a^4)b/5b)}}} if {{{a = -1}}} and {{{b = 2}}}
{{{sqrt(80((-1)^4)cross((2))/5cross((2)))}}}
{{{sqrt(80/5)}}}
{{{sqrt(16)}}}
{{{highlight(4)}}} or {{{highlight(-4)}}}
