Evaluate 3-1/3^4
I need in fraction form

242/81

Step-by-step explanation:

This is the order that your calculation needs to go in.

So the question states 3 - (1/3)^4

So first we work out 1/3^4 which is 1/3 x 1/3 x 1/3 x 1/3

This becomes 1/81

Then you do 3 - 1/81 which becomes 242/81

3/1 - 1/81

243/81 - 1/81 (after finding the LCM of the denominator)

242/81

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

factor trees are nice.
