Question

Need this QUICK!! Evaluate without using a calculator (x2y-3)0+x1/3-(4x)1/2 when x = 64 and y = 27.Show work

Answer 1

-11

Explanation:

Given the expression

(x²y-3)⁰+x^1/3-(4x)^1/2 when x = 64 and y = 27.Show work

Note that anything raise to power of zero is 1, hence (x²y-3)⁰ = 1

x^1/3

= 64^1/3

= ∛64

= 4

(4x)^1/2

= (4* 64)^1/2

= 4^1/2 * 64^1/2

= 2 * 8

= 16

Substitute;

(x²y-3)⁰+x^1/3-(4x)^1/2

= 1 + 4 - 16

= 5 - 16

= -11

Hence the required value is -11
