Use order of operations... PEMDAS - the order you should attack all math problems.

Parentheses
exponents
multiplication
division
addition
subtraction

So you have to do the exponent THEN the multiplication

3a^2 =
3*8^2 =
3 * 64 =

Find the derivative of the function. y = sin−1(6x + 1)
liraira [26]

If you don't know the derivative of the inverse of sine, you can use implicit differentiation. Apply sine to both sides:

y=\sin^{-1}(6x+1)\implies\sin y=6x+1

(true for <em>y</em> between -π/2 and π/2)

Now take the derivative of both sides and solve for it:

\cos y\dfrac{\mathrm dy}{\mathrm dx}=6

\dfrac{\mathrm dy}{\mathrm dx}=6\sec y

\dfrac{\mathrm dy}{\mathrm dx}=\dfrac6{\cos\left(\sin^{-1}(6x+1)\right)}

\dfrac{\mathrm dy}{\mathrm dx}=\dfrac6{\sqrt{1-(6x+1)^2}}

If f(x) varies directly with x and f(x) = 48 when x = 8 find the value of f(x) when x = 2
const2013 [10]
Here, f(x) = kx

k = f(x)/x
k = 48/8
k = 6

So, when x = 2, 
f(x) = 6 * 2
z = 12

In short, Your Answer would be: 12

Hope this helps!
