At time t=0 hours a tank contains 3000 litres of water .
water leakes from the tank.
at the end of every hour there is a x% less water in the tank then at the start of the hour
the volume of water in litres, in the tank at time t hours is v1.
given that v1=k^1v0
v2=2881.2
work out the value of k and value of x

is only a line? i think so

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
