Identify the greater number, wherever possible, in each of the following ? (i) `4^3 or 3^4` (ii) `5^3 or 3^5` (iii) `2^8 or 8^2` (iv) `100^2 or 2^100`

Answer» (i) `4^3 or 3^4`
`4^3 = 4*4*4 = 64`
`3^4 = 3*3*3*3 = 81`
`:. 3^4> 4^3`
(ii) `5^3 or 3^5`
`5^3= 125`
`3^5= 243`
`:. 3^5> 5^3`
(iii) `2^8 or 8^2`
`2^8 = (2*2*2*2)^2 = 16^2= 96`
`8^2 = 64`
`:. 2^8 > 8^2`
(iv)`100^2 or 2^100`
`100^2 = 10000`
`2^100= (2^10)^10 = 1024^10`
`:. 2^100 > 100^2`
