Select the correct answer. Which expression is equivalent to 13 square root 22b - 10 square root 22b, if b>0?

A. 23 square root 22b
B. 130 square root 22b
C. 3 square root b^2
D. 3 square root 22b

Given:

The expression is

To find:

The equivalent expression.

Solution:

We have,

Taking out common factors.

The expression is equivalent to the given expression.

Therefore, the correct option is D.

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

y > 1/3x

y < = -x + 4

hope this : )
