Which of the following numbers is irrational?

i believe the answer to your problem is D.

Reason: * The Square Root of 2, written as √2, is also an irrational number. The first part of this number would be written as 1.41421356237…but the numbers go on into infinity and do not ever repeat, and they do not ever terminate. A square root is the opposite of squaring a number, meaning that the square root of two times the square root of two equals two.  This means that 1.41421356237… multiplied by 1.41421356237… equals two, but it is difficult to be exact in showing this because the square root of two does not end, so when you actually do the multiplication, the resulting number will be close to two, but will not actually be two exactly. Because the square root of two never repeats and never ends, it is an irrational number. Many other square roots and cubed roots are irrational numbers; however, not all square roots are.

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5
