1/2x^3

I assume 8x to 5th is in denominator 4x^2/8x^5 = x^2/2x^5 = 1/2x^3 = 0.5x to the negative 3

if you mean (3/(2x-5))(21/(8x2-14x-15)) you would get (63/( (2x-5)(4x+3)(2x-5) ) simplified more would be 63/ ( (2x-5)2(4x+3) )

4x^2
4x^4 or 4x*4x*4x*4x A formula would be (x^a)(x^b)= x^a+b x^a) / (x^b)= x^a-b

(4x - 7y)(4x + 7y)
The GCF is 4x.
It is 1/(4x)2
