To solve this question you want to do it step by step. Firstly replace the 'a' with '4' and calculate the first part of the sum. 4 multiplied by 4, which is 16. Next replace 'b' with '3' and calculate the se...

In order to solve this set of simultaneous equations, we will rearrange each equation to use substitution. The aim of this problem is to find out what the value of x and y is. Let's rearrange equation 1 and ...

A quadratic equation is an equation of the form y = a x 2 + b x + c where a, b and c are constants (for example 5, -2 or 0). To "solve" a quadratic equation we are finding the values of x that sati...

When we integrate a function we must first raise the power of x in each term by one. The first term therefore becomes x^(5/2). The second term can be thought of as x^0 which we know that any number to the po...

To solve this problem, you need to put it into simplest form which is putting it into natural logarithm both the RHS and LHS. Then differentiate both side with respect to x as shown below. In(y) = ln(x^x) - ...
