Question

Work out the following without using a calculator (show working out) please help

1)17^0/2^2
2)27^2/3/3^2
3)64^1/2/4^2
4)1^0/2^3

Answer 1

1: 17⁰ / 2² = 1 / 4

2:

`27^{(2)/(3)} / 3^(2)\\= {\sqrt[3]{27}}^2 / 3^2\\= 3^2 / 3^2\\= 1`

3:

`64^{(1)/(2)} / 4^2\\= 8 / 16\\= 1/2`

4: 1⁰ / 2³ = 1 / 8
