That depends on the order of operations you're trying to convey.
If you mean (1/4) * √(16) / 5, then the answer is:
(1/4) * √(16) / 5
= √(16) / 20
= 4/20
= 1/5
If you mean (1/4) * √(16 / 5), then the answer is:
(1/4) * √(16 / 5)
= √(16 / 5) / 4
= 4 / 4√5
= 1 / √5
And to put it in the proper format (radicals in the numerator):
= √5 / 5
Negative fourth root of a number= 1/the fourth root of the number. Fourth root of 625= 5 (5*5*5*5) 1/5

'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.
6251/4 = 5
It is +25
The square root of (any number that isn't a perfect square) is irrational.
16
16 and 1 fourth
sqrt(16/25) = sqrt(16)/sqrt(25) = ±4/±5 = ±4/5 or ±0.8
16 to the power (1/2) is the same as the square root of 16 - that is, 4.16 to the power (1/2) is the same as the square root of 16 - that is, 4.16 to the power (1/2) is the same as the square root of 16 - that is, 4.16 to the power (1/2) is the same as the square root of 16 - that is, 4.
what number times itself = 16, that is what you are trying to find. 4 x 4= 16 so the square root of 16 =4 square root of 25 is 5 because 5 x 5 is well 25.
b over the square root of 5 The square root of 5b squared is 5b, and the simplified form of the square root of 125 is 5 root 5. The 5s then cancel out leaving b over the square root of 5.
