# "Recall that the definition of the absolute value of a " #
# "complex number," \ a + bi \ \ "is:"#
# \qquad \qquad \qquad \qquad \qquad \qquad \qquad \qquad | a + bi | \ = \ \sqrt{ a^2 + b^2 }. #
# "So, we have now:" #
# \qquad \qquad \qquad | 7 + 7i | \ = \ \sqrt{ 7^2 + 7^2 } \ = \ \sqrt{ 2 \cdot 7^2 } \ = \ 7 \sqrt{ 2 }. #
