We want to get the the sqrt(27) and sqrt(192) so that they have the same number in the square so they can then be added together. We will look at the factorisation of 27, 192. We can see 27 is divisible b...

The answer should always end with x = …, so we need to rearrange and simplify the equation to solve this.First write out the full equation: x + 1 = x/2 + 4Multiply everything by 2 to remove the fraction: ...

as ln x is not a standard integral given in the formula booklet, but it’s derivative is a standard derivative, you can split ln x into 1 times ln x. This allows you to use the integral product rule method...

X=0,-5,1

The probability on the spinner for each section is 0.2 or written a 2 in 5 ( 1 divided by 5 as it has equal sections)
The probability for landing the green side of the dice is 1 in 6
In order ...
