9^(1/2)=sqrt(9)

Ok, great. Some of us are looking for the "how" rather than the "why". 2**5=32, yes? I can write this down as 2*2=4, 4*2=8, 8*2=16, and finally 16*2=32, and so therefore can count the #2 five individual times whereas I'm unable to see the same logic in 9**(1/2).

Help me with this >>> 2**5
32
>>> 9 ** (1/2)
3.0 how is this possible
2*2*2*2*2=32 ✓
9*0.5= 4.50 X(it should be 3.0)
Please help me with this

+ 7

because anything raised to the power of 0.5 is square root

+ 6

sqrt of 9 is 3 and it's a double value so 3.0

+ 3

>>> 9 ** (1/2)
9*0.5= 4.50 X(it should be 3.0)
Could you explain with this.

Explanation:
9 power 1/2
As we know that 1/2=√
So,
9 power 1/2=√9=3
As Python silently convert Interger into Float
So, Ans is 3.0

I have been trying to figure it out as well so not 100% sure on my explanation.
Squareroot of 9 = put 9 dots in a squate and What's the number of dots on X and Y axis.
. . .
. . .
. . .
the root of this square with 9 dots is 3
9**(1/2)= 3*3
8**(1/3)= 2*2*2
4**(1/2)= 2*2

omg.. I'm intimidated

** is the to the power of function , when you raise a number to the power of 0.5 it is the same as taking the square root of the number , the square root of 9 is 3 .

This is math.
The exponent of a root can be placed in an exponent as the denominator of a fraction.
V meaning root, and ^ exponent:
2V9^1 = 9^1/2 (= 3)
reads: the second root (squareroot) of nine to the power of one (which is just nine) is equals as nine to the power of one over two.
3V27^1 = 27^1/3 (= 3)
reads: the third root of twenty-seven is equals to 27 to the power of one third.
So you see, the exponent of the root wanders to the exponent of the number, but below the fraction bar (denominator).
3V8^2 = 8^2/3 (= 4)
2V4^3 = 4^3/2 (= 4)
I hope this is logical... somehow... ^_^

Square root of 9 is 3

I can't understand how ( 9 ** (1/3) ) = 0.3

The simple and correct,real answer is that
Which number can be equal to nine when it

- 1

9 raised to the power (1/2) is the same as the square root of 9.
I.e 9^(1/2) = sqrt (9) = 3.0
