-9x5 over the square root of x plus 4?

Answer 1

(-9x^2/√x) + 4

= [-9x^2/x^(1/2)] + 4

= (-9x^2)[x^(-1/2)] + 4

= -9x^[2 + (-1/2)] + 4

= -9x^(2 - 1/2) + 4

= -9x^(3/2) + 4

= -9√x^3 + 4

= -9√[(x^2)(x)] + 4

= -9x√x + 4

Or,

(-9x^2/√x) + 4

= [(-9x^2)(√x)/(√x)(√x)] + 4

= [(-9x^2)(√x)/√x^2] + 4

= [-9(x)(x)(√x)/x] + 4 simplify x

= -9x√x + 4
