Which number is an irrational number a. 0.6 repeating b. 9/27 c.9/16 squared root d. 9/27 square root

D is an irrational number because it equals 0.577350269

D

Step-by-step explanation:

the square root of 9/27 will equal to square root of 3 over 3.

A will simplify to 2/3.

B will simplify to 1/3.

C will simplify to 3/4.

As long as the number has a square root somewhere in the final answer, it will be irrational.

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
