[1/1 Formula]
Work: Calculate the value of equation √(1+20^2)/(1*√((1+20^2/4)*((1-20^2/9)^2+20^2/9))) .
Question type: Mathematical calculation
Solution:
√(1+20^2)/(1*√((1+20^2/4)*((1-20^2/9)^2+20^2/9)))
=√401/(1*√((1+20^2/4)*((1-20^2/9)^2+20^2/9)))
=√401/(1*√(101*((1-20^2/9)^2+20^2/9)))
=√401/(1*√(101*((-43.444444)^2+20^2/9)))
=√401/(1*√(101*1931.864158))
=√401/(1*√195118.279958)
=√401/441.721949
=20.024984/441.721949
=0.045334
Answer:√(1+20^2)/(1*√((1+20^2/4)*((1-20^2/9)^2+20^2/9)))=0.045334
