Question 716206
Please re-post your question and put the radicand in parentheses. ("Radicand" is the name for the expression inside a radical.) The way you posted the expression it is impossible to tell if it is:
{{{sqrt(7)s/4}}}
or
{{{sqrt(7s)/4}}}
or
{{{sqrt(7s/4)}}}
Problems that are unambiguously posted are more likely to get quick responses. These three expressions have three very different solutions and tutors are unlikely either to guess which one is right or to solve all three problems.
