Question

please solve it guys it is my homework please guys help me ​

Answer 1

Answer:

1) 0.00000000081

2) 6254 x 10^(-5)

3) 2^(10) x 3

Explaination:

In Question 1 , the power in -10,

So, the point will move from 8.1 to 0.00000000081

Thus, 0.00000000081.

In Question 2 , 6254/100000 =6254/10^5

so it will become 6254 x 10^(-5)

In Question 3,  2^(12)-2^(10),

So, Take 2^(10) common to form:

2^(10) x (2^2-1)

2^(10) x (4-1)

Thus , 2^(10) x 3

(Hope this will help freind)
