Simplify and express with positive indices, a little help?
I am no good at these, can anyone show me how to work these out?

(18x3 X 2x-4)/(4x-5 X 6x)

83sqrt(p12 q-8) X 34sqrt(p-10 q9)

and

(6x+2 X 42x-4 X 35-x X 2x-6)/(124x+3 X 92x-3)

ps. The Capital X's are multiplication signs

Then, obviously, you need to work to get good at these.
(18x3 X 2x-4)/(4x-5 X 6x)

83sqrt(p12 q-8) X 34sqrt(p-10 q9)

and

(6x+2 X 42x-4 X 35-x X 2x-6)/(124x+3 X 92x-3)

ps. The Capital X's are multiplication signs
Review the properties of exponents (or indices, as you call them), especially these:
[tex]a^m \cdot a^n = a^{m + n}[/tex]

[tex]\frac{a^m}{a^n} = a^{m - n}[/tex]

[tex](a^m)^n = a^{m \cdot n}[/tex]

Also,
[tex]\sqrt[n]{x} = x^{1/n}[/tex]
