Question 87506
What was the question?  Were you supposed to determine which two expressions have the same value???


{{{sqrt(-49) }}} is not a real value (or if you consider complex numbers, the value is 9i.


{{{-sqrt(49)= -7}}}


I suppose if you want two that are equivalent, it would be {{{ -7}}} and {{{-sqrt (49)}}}.
