7xy+3y2=10x 3y2=10-7xy 3y2=x(10-7y) 3y2/10-7y=x

solve 64^2/3 ... note X^2/3 = X^{2 x 1/3} therefore 64^2/3= (64²)^1/3= (4096) ^1/3= 16

Find the value of 9^-1/2. For this question we need to know indices rules. We apply two rules here as the power is negative and because it's a fraction. First, let's tackle the negative power ru...

We know the presence of the quadratic means there must be two solutions for x. We can solve this problem by treating the formulas for the graphs as simultaneous equations. We can substitute in the formula...

Lets take 18 and 48 as our two numbers for an example.
Break both down into products of their prime factors using factor trees: 18=3x3x3x2 and 48=3x2x2x2x2.
Write the prime factors as a Venn dia...
