What is the value of 2x(^0) + 5x(^-½) / x(^-3/4)?

Question

a 9/4

b 11/4

c 26

Answer 1

x^0 = 1

x^-1/2 = 1 / square root (x)

x^-3/4 = 1 / fourth square roo(x^3)

[5 + 2·square root (x) / square root (x)] / (1 / fourth square root (x^3))

[5 + 2· square root(x) · fourth square root (x^3)] / square root (x)

In any case, you can't know the solution as you don't know "x" value
