Answer:
2^1.4 = 2.6390...
Step-by-step explanation:
2^1.4 = 2.6390...
Using log and antilogs i.e not easy approach ?
i.e.
log y = log m^n
log y = n log m
log y = 1.4 log 2
log y = 1.4 * 0.301
log y = 0.4214
antilog (log y) = antilog 0.4214
y= antilog 0.4212 (look for this in a table, should give result)
What I found on internet ,
turn the decimal into a fraction
2^(1.4) => 2^(1 + 2/5)
now given a^(n + m) = a^n * a^m => 2^1 * 2^(2/5) => 2 * 2^(2/5)
you can stop there if you want to.
however a^(nm) = (a^n)^m
=> 2 * (2^2)^(1/5)
