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
Answer:
1) 30
2) 4.5
Step-by-step explanation:
<span>Thus, a product that normally costs $199 with a 5 percent discount will cost you $189.05, and you saved $9.95.</span>
<span>You can also calculate how much you save by simply moving the period in 05.00 percent two spaces to the left, and then multiply the result by $199 as follows: $199 x .05 = $9.95 savings.</span>
<span>Furthermore, you can get the final price by simply deducting .05 from 1 and multiplying it by $199 as follows: (1 - .05) x $199 = $189.05 final price. </span>
<span>If something costs $199 and is on sale for 5% off, then how much would it cost? Here we will show you how to calculate how much you save (discount) and how much you have to pay if something you want to buy is regularly $199, but is currently on sale for 5 percent off.
<span>$199
<span>SALE
</span>5% OFF</span>
There are many ways of calculating your discount and final purchase price. One way is to multiply 199 dollars by 5 percent, and then divide the answer by one hundred, then deduct that result from the original price. See illustration below:
+ Purchase Price = $199
- Discount (199 x 5)/100 = $9.95
<span>= Final Price 199 - 9.95 = $189.05

Step-by-step explanation:
So it could be GREATER than 46
.85 x = 46 <u>x = 54.11 cm^3 </u>
Or it could be smaller than 46
46= (1.15) x <u> x = 40 cm^3 </u>
