REMEMER that for any indices, lower the base higher the power is always greater if ssum of terms is same.
for 5^7 means 5 seven times so sum is 35
and for 7^5 means 7 five times so sum is 35. by using the rule 5^7 is greater.
for example, 3^4 is greater than 4^3.
3^333 is greater than 333^3 and for any term. bus rememberits not true numbers less then 3. i mean 2^3 is not greater than 3^2
On Array email@example.com wrote
5^7 = 25 * 25 * 25*5
7^5 = 49 * 49 * 7 = Equivelent to = (25 * 2) (25 * 2 ) * (5)
so 5^7 is much bigger ...
there is no short cut for these type of problems
lemme know if any one has some comments ..
