Answer 2

Step-by-step explanation:

5.(I) (√4) ^(-3)

= 2 ^ (-3)

= 1/8

--------------------------------------------------------------

(ii) (√5) ^(-3) × (√2)^ (-3)

= (√5 × √2) ^(-3)

{ Using (a)^x × (b)^x = (ab)^x }

= (√10) ^ (-3)

= (10) ^ (-3/2)

= 1/√1000 ---------------------------------------------------

(iii) (Cube root of 8)^(-1/2)

= 2 ^ (-1/2)

= 1/(√2)

Here ' ^ ' means Raised to the power.
