The answer is, 24x
5x
The answers are ± 625
ok lets let x=4. The square root of 4 to the 2nd power + 4= 8. The square root and power of 2 cancel out? Is that what you mean?
x^2 = 54; take the square root of both sides, so x = +/- square root of 54 , or simplified is +/- 3 times square root of 6.
Press 2ND and then the square root sign (above x2). Then type the number you want to find the square root of. Press ENTER to see the answer.
square root of c to the second power is c

Isnt that just the square root of 64, being 8...?
(5x - i)(5x + i) where i is the imaginary unit equivalent to the square root of negative one.
(5x - i)(5x + i) where i is the imaginary unit equivalent to the square root of negative one.

x^2 plus 4 = 0x^2 = -4square root both sidesx = the square root of -4x = 2i
