(i) 32 (ii) 243 (iii) 100000 (iv) 1024

3125​

Answer 1

Answer:

$1. \: \sqrt[5]{32} = 2 \\ 2. \: \sqrt[5]{243} = 3 \\ 3. \: \sqrt[5]{100000} = 10 \\ 4. \: \sqrt[5]{1024} = 4 \\ 5. \: \sqrt[5]{3125} = 5$

Hope you found my answer helpful. Keep Smiling!

Answer 2

We have , 32= 2^5
So, (32)^1/5=2^5×1/5=2
243=3^5
so its 5th root is 3
100000= 10^5
so its 5th root is 10
1024= 4^5
so its 5th root is 4
