ANSWER
0.1
EXPLANATION
We want to estimate the quotient of 1.64 ÷ 22.
To do this, we will approximate the two numbers to whole number and solve it.
It becomes:
2 ÷ 20
That is:
Note: since 2 cannot be divided by 20, we write 0. and add a 0 to the back of 2.
The estimate of the quotient is 0.1.
Do you mean the following:
log(5^(4/7))=around 0.4
log(5)^(4/7)=around 0.815
log(5^4)/7= same thing as top one
log((5^4)/7)=around 1.95
16 ounces in a pound
16*3=48
48 ounces of mixed nuts
Even functions (like this one) are symmetric to the y-axis. So even if you reflect it over the y-axis it will look the same :)
I believe the answer is 5x
