The simple interest on Rs 1650 will be less than the interest on Rs 1800 at 4% simple interest by Rs 30 find
the time

prt/100

1650*4*1/100 = 66

1800*4*1/100 = 72

then 72-66 = 6

6 = 30 then 1 = 5 ans.

plz give me the brainliest i need it

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
