first of all, have a look at each side separately to see you you can cancel anything down.e.g. the square and square root can cancel out. => sq.root(6²+8²) = 6+8on the otherside, ...

27^-2/31/(27^2/3)1/(27^1/3)²1/3²= 1/9

To find 125^1/3 we have to solve x³ = 125 => This gives x=5 Then we have 2^-3 is equal to 1/(2³) => This is equal to 1/8So to answer the question we have 5*...

(x+a)(x+b) = 0The two numbers must have a product of 12 and a sum of 7.3*4 = 12 AND 3+4=7Therefore(x+3)(x+4) = 0Therefore x+3 = 0 --> x = -3OR x+4 = 0 --> x = -4

The first step to writing an expression with more than one fraction as a single fraction is to find their lowest common denominator. For example, in a question with two fractions where the denominators ar...
