Question

$fraction numerator 1 over denominator r subscript 1 end subscript superscript 2 end superscript end fraction$ + $fraction numerator 1 over denominator r subscript 2 end subscript superscript 2 end superscript end fraction$ + $fraction numerator 1 over denominator r subscript 3 end subscript superscript 2 end superscript end fraction$ + $fraction numerator 1 over denominator r subscript blank superscript 2 end superscript end fraction$ =

$\frac{a^{2} + b^{2} + c^{2}}{s^{2}}$
$\frac{\sum a^{2}}{S^{2}}$
4R
4r

The correct answer is: $fraction numerator sum a to the power of 2 end exponent over denominator S to the power of 2 end exponent end fraction$
