25×(1−0.18)^(4)
=11.30

25*0.01=25(1-0.18)^t
0.25=25(0.82)^t
0.25/25=(0.82)^t
t=log(0.25/25)/log(0.82)
t=log(0.25÷25)÷log(0.82)
t=23.21 hours

choli [55]

Answer:

\frac{1}{4} or 0.25 (they're the same)

Step-by-step explanation:

First Part:

  1. 4^{3} = 64  
  2. 8^{2} = 64  
  3. 2 = 2  
  4. Multiply them together: 64 × 64 × 2 = 8192

Second Part:

  1. 2^{7} = 128  
  2. 16^{2} = 256  
  3. Multiply them together: 128 × 256 = 32768

Wrap it all up:

  1. 8192 ÷ 32768 = 0.25 = 1/4

I hope this helps!
