Rohit will get paid on the tenth day. How much money is it?​

Answer 1

Answer:

He will get 512 rupees at the 10th day.

Step-by-step explanation:

Start from day 0 he will get 1 rupee

1st day he will get 2 rupees

So on doubling each day

Go till day 9 to get 512

So the exponent will be 15×2 to the power 5

Answer 2

Answer:

512

Step-by-step explanation:

Let the value be x.

1st day= 1x

2= 2x

3= 4x

4= 8x

5= 16x

6= 32x

7= 64x

8= 128x

9= 256x

10= 512x

x = 1 (for convenience)

Just double it till the 10th day
