Question

Simplify (0.00243)^-2/5 x (0.0009)^1/2

Answer 1

1/3

Explanation:

(0.00243)^-2/5 x (0.0009)^1/2

= 1/(0.00243)^2/5 x (0.0009)^1/2

= 1/0.3² × 0.03

= 1/0.09 × 0.03

= 1/3

Answer 2

(0.00243)^-2/5 x (0.0009)^1/2

= (243/100000)^-2/5 x (9/10000)^(1/2)

= ((3/10)^5)^-2/5 x ((3/100)^2)^(1/2)

= (3/10)^-2 x (3/100)

=1/(3/10)^2 x (3/100)

= (100/9) x (3/100)

= (1/3)

Hope this helps!
