<h3>Answer: Choice C</h3><h3>which is the expression 4*sqrt(5)*i,  where i = sqrt(-1)</h3>

==================================================

Explanation:

Factor -80 in such a way where we pull out -1 and we also factor out the largest perfect square possible. In this case, it would be 16 because 80 = 16*5. So this means -80 = -1*16*5 which leads to...

sqrt(-80) = sqrt(-1*16*5)

sqrt(-80) = sqrt(-1)*sqrt(16)*sqrt(5)

sqrt(-80) = i*4*sqrt(5)

sqrt(-80) = 4i*sqrt(5)

sqrt(-80) = 4*sqrt(5)*i

belka [17]

Answer:

Widow's Share = Rs 500.05

Son's share = Rs 1400.14

Step-by-step explanation:

Property = 4000.40

Widow get share = 0.125

So, Share of Widow = 0.125 * 4000.40

Widow's Share = Rs 500.05

Remaining Property = 4000.40 - 500.05

Remaining Property = 3500.35

Son's share = 0.4 * 3500.35

Son's share = Rs 1400.14

Step-by-step explanation:

The first term is already given it is 10.

The second term is the first term times 2.2.

10×2.2=22

The third term is the second term times 2.2.

22×2.2=48.4

The third term is 48.4.

The fourth term is the third term times 2.2.

48.4×2.2=106.48

The fourth term is 106.48.

The fifth term is the fourth term times 2.2.

106.48×2.2=234.256

The fifth term is 234.256.
