what is 27^(-1/2)? thanks. i don't have my calculator on me.
well, that's the same as 1/(square root of 27).. so if you simplify it, you will end up with 1/(3square root of 3).
To find the value of 27^(-1/2), we can first simplify it as 1/(square root of 27).
To calculate the square root, we can break down 27 into its prime factors. 27 is equal to 3 * 3 * 3.
Next, we can simplify the square root of 27 by taking out two 3's from under the square root sign, leaving only one 3 inside. This gives us the square root of 27 as 3 * square root of 3.
Now, we can substitute this simplified form back into our original expression: 1 / (3 * square root of 3).
So, the value of 27^(-1/2) is 1 / (3 * square root of 3), or equivalently, 1 / (3√3).
