5 to the power of 4 in standard form is: 5x5x5x5
3^5*4^5 = (3*4)^5 = 12^5
It is: 8^4 times 8^5 = 134217728
4^5 5 is the exponent.
Your question is AMBIGUOUS. (4 over 5) to the 4th power is (4/5)*(4/5)*(4/5)*(4/5) which is(4*4*4*4)/(5*5*5*5) = 256/625.But 4 over (5 to the 4th power) is 4/(5*5*5*5) = 4/625
