How do you explain that √(m+n)=√m+ √n is not true for all values? (example: m=5 and n=4)

Square the expressions to see the difference.

Step-by-step explanation:

.

Squaring this we have:

Now,

Squaring this we get:

For the two expressions to be equal, we should have

⇔ .

This is possible iff mn = 0. i.e, m = 0 or n = 0.

Otherwise, they are not equal.

When m = 5 and n = 4.

First is an integer. Second is an irrational number.

Clearly, they are not equal.

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

felicia:

260 words per minute

200< 260 < 265

connie < felicia < stew

think about it deeply and passionately about this property
