The expression can be simplified as:

k^3(k7/5)^-5
= k^(3+-5) * (7/5)^-5
(Collecting the powers of k at one side and the constants at other side)
= k^-2 * (5/7)^5
(Solving thr integer powers)
= k^-2 * (3125/16807)

ale4655 [162]

Answer:

Given: Water in a reservoir dropped by 60%

Step-by-step explanation:

let the total water level of reservoir be 100.

then, in first year

the water reservoir dropped = 60% of 100

= $\frac{60}{100}$ * 100

= 60

therefore, total water level needed to be restored till next year= 100

remaining water level to restore till next year= 100-60

=40

percentage= $\frac{40}{100}$ * 100

=40%
