Step-by-step explanation:
The question is incomplete, as the 8 expressions are not given.
The general explanation is as follows
As complex as an expression may seem, you have to simplify each expression until it cannot be further simplified.
Then you categorize each result, depending on if it equals 
or not
Take for instance:
Using law of indices:
---- equivalent
Factorize the numerator
Cancel out 2
Apply law of indices
---equivalent
Express as exponent
Apply law of indices
---- equivalent
Solve exponents
---- not equivalent
20000+6000=26000 hope it helps
Answer:
399.420
Step-by-step explanation:
1) Use the algorithm method.
4 7 . 5 5
× 8 . 4
1 3 2 2
1 9 . 0 2 0
3 6 4 4
3 8 0 . 4 0 0
3 9 9 . 4 2 0
2) Therefore, 
.
399.420
Since 34 only goes into 7 four times the answer is 28 with a remainder of 6:) so basically you would could by your 7s so 7, 14, 21, 28, 35 and since 35 is too much we would have to go with 28. so then we subtract 28 from 34 and that gives us 6 left over. hoped this helped:))
For Example 3 :
First blank is cos (theta)
Second blank is sec(theta)
For Example 4 :
First blank is (x^4)/(2) - (3x^2)
Second blank is 0
Third blank is -4
Fourth blank is 0.4286
Hope this helps :)
