10 squared is 100. 20 squared is 400. 225 is between 100 and 400. Its square root will be between 10 and 20.
- sqrt(1) - sqrt(-400) = -1 - 20i, where "i" is the imaginary unit.- sqrt(1) - sqrt(-400) = -1 - 20i, where "i" is the imaginary unit.- sqrt(1) - sqrt(-400) = -1 - 20i, where "i" is the imaginary unit.- sqrt(1) - sqrt(-400) = -1 - 20i, where "i" is the imaginary unit.
About 28.28 ft. You can solve this as a right triangle problem. Multiply each side x itself (square it) that Is 400. Add the squares of the two sides (400+400= 800). Then find the square root of 800, which is 28.28
The 8th root
They are: 324, 361 and 400 inclusive
Square root 400 - square root 196 = 6
