Using the grid method, we know this is equal to (10100) + (1020) + (7100) + (720) = 1000+200+700+140 = 2040

If a number is to the power of 2/3, you should think of it as to the power of 1/3 (so CUBE-rooted), and then being to the power of 2 (so squared).

So here, the cube root of 64 is 4, because 4x4x4=6...

The easy way to remember these uses the acronym SOH-CAH-TOA

The function to use depends on the sides of the triangle you know in the problem. 

With right angled triangles each side has a nam...

Pythagoras theorum is used to identify the lengths of any side on a right angle triangle. The theorem is as follows:

a²  + b² = c²    

We assume that the hyp...

Begin by looking at the percentage reduction: 

100% - 35% = 65%

Therefore, 65% = £16 (as this was the price it was reduced to)

1% = £16 ÷ 65 = 0.2462

So to find the ...
