Question

Help!

I need help for ques. 25-30 only!

My professor didn’t want to come to class today and assigned a sub, which only gave us our hw and didn’t teach us anything about the lesson.

Answer 1

Answer:

25,the answer is 55555.t

Answer 2

Yo

25.

-3

cause when you multiply you should get -6

2*X=-6

hence X=-3

26.

6+X=9

X=3

27.

25-X=6

X=19

28.

Cause the power of denominator becomes negative which on addition to the power of numerator gives subtraction.

Also the common terms gets cancelled which can also be obtained by subtraction.

29.

mass of sun in metric ton=2*10^(27)

mass of sun in kg=2*10^(30)

By applying unitary method we get

X=2*10^(30)/2*10^(27)

=10³

Hence 1 metric ton=10³ kg

30.

1TB=2^(10)*2^(30)

=2^(10+30)

=2^40 bytes

Hope this helps
