in your radicand you have... (-5)2 - -4 x 3 x 3
this is equal to 61
remember the order of operations.
PEMDAS
P=parenthesis
E=exponents
M=multiplication
D=division
A=addition
S=subtraction
In your problem you first have to do the exponents. then you multiply the -4, 3, and 3 and the you add.
therefore your answer is sqrt(61) which is 7.81
