So i dont get your question. do you need to find out what 3x10^-2 is?
Adding is where you added, or put something with, a number.
f(x)=4x
To find the inverse, first change f(x) to y:
y = 4x
Now switch the variables:
x = 4y
Solve for Y:
Divide both sides by 4:
y = x/4
Now replace y with the inverse function f^-1(x):
f^-1(x) = x/4

Answer:
Step-by-step explanation:
rather than doing all of the sums, you should just learn the formula (for the pattern)
it is <u>n(highest + lowest)</u> where n is number of numbers

for example 2+3+4+5+6 = 20
<u>5(6+2)</u> = 20

~~~~~~~~~~~~~~~~~~~~
1+2+3+4+5+6+7+8 = 36
<u>8(9)</u> = 72/2= 36
