Answer:

Step-by-step explanation:
Some facts to establish before we try to solve:
and another way of writing
is
. Also order of operations: PEMDAS
For the first option:
We solve what is in the parenthesis: 2*2=4*2=8*2=16*2=32*2=64 so
, which is another way to write
For the second option: If the square root of 64 is 8, the there is no way we can multiply another value by it.
The third option: When dealing with square roots, we can solve the inside first and then take the square root:
definitely not 64 (though if you're curious it's 4096)
The fourth: Another way to write the square root is to raise the value to the 1/2 power so

Which is the same as 
Fifth: Like the third, we solve the inside of the square root first
16*4= 64 and then 
Sixth: We need a nice whole number (8), and
has no clean roots, so its result will have decimals. It can't be our answer

When e=12 and
.
Substitute e=12 and
in the given expression.

On simplification we get


Therefore, the value of given expression is 1.
Answer:
Step-by-step explanation:
The number of miles that he ran last week is m.
His goal this week was to run one mile more than twice the miles he ran last week. This means that his goal this week is
m + 2m = 3m
If he tripled his goal, it means that the number of miles that he ran this week would be
3 × 3m = 9m
An expression in simplest form to show how many more miles he ran this week compared to last week would be
9m - m = 8m
