What is 5 and 16 over 25 as a decimal?
5 16/25 as a decimal = 5.64
If 5 is the square root of 25 what is the square and what is the square root?
'Squared' & 'Square Root; are the inverse mathemtical functions. 5 (squared) = 25 square root of '25' is 5 Mathematically this would be written as Square ; 5 x 5 = 5^(2) = 25 Square Root ; sqrt(25) = 25^(1/2) = 25^(0.5) = 5 NB THis can be exteneded to 'cubes' and 'cube roots' e.g. 3 x 3 x 3 = 3^(3) = 27 curt(27) = 27^(1/3) = 27^(0.3333.....) - 3 And fourth power and fourth root. e.g. Fourth power ; 2 x 2 x 2 x 2 = 2^(4) = 16 Fourth root = (4th)rt(16) = 16^(1/4) = 16^(0.25) = 2 It can be exteneded to the 'nth power' and the 'nth root'. Where 'n' is any number.
What is the next number in the series 1 4 16 25?
1, 4, 16, 25 are all square numbers: 1^2, 2^2, 4^2, 5^2 1+1=2, 2+2=4, 4+1=5. I guess the next basis number is 5+2=7 (+1,+2,+1,+2,+1,...) So I would guess: 1 4 16 25 49 64 100 121 ...
How do you solve 2 16 over 25?
2 16/25 = 2.64
