f(x) = x2 - 3
By the power rule:
f'(x) = 2x2-1 - 0
= 2x
f''(x) = 2(1)x1-1
= 2
The second derivative of x2 - 3 is 2.
The derivative of ANY constant expression - one that doesn't depend on variables - is zero.
Find the square root of each of its components, and muliply them together. For example, 36x8 the square root of 36 is 6 the square root of x8 is x4 so the square root of 36x8 is 6x4
Use a calculator. Most will allow you to find 70(1/4) Or find the square root of the square root of 70.
The same way as you find the square root with an even-numbered exponent. For example, the square root of x10 is x5. That is, divide the exponent by 2. Similarly, the square root of x7 is x3.5. Once again, you simply calculate one-half of the exponent. If you prefer to express this with integer exponents and square roots, in this example you can write x3.5 as x3x0.5. The second part, x0.5, is equivalent to the square root of "x".
The same way you find the square root of any number. The fastest way would be to type 225, followed by the square root key, in a calculator.
