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
258
4-3 x 4-5 = 1.5265625 × 10-5
y^9
power forward is 4, center is 5
5 to the 7th power
4 to the power of 5
5 to the power of -2
5 to the power of 4 in standard form is: 5x5x5x5
3^5*4^5 = (3*4)^5 = 12^5

53 * 54 = 5(3+4) = 57 = 78125
