If x5y4z2 <0 , which of the following must be true?
devlian [24]

In order for the whole expression to be negative, either  (x⁵) 
or  (y⁴)  or  (z²)  must be negative.

But an even-numbered power can't be negative ... even if the base
is a negative number, any even-numbered power of it is positive.

So  (y⁴)  and  (z²)  are always positive.  The expression can be
negative if 'x' is negative, because  (x⁵)  will then be negative.

None of the proposed requirements is appropriate, so the
final answer is  E. None .

Simplify the square root of 147
Sergio [31]

Answer:

7√3

Step-by-step explanation:

To simplify a square root, look for some of its factors. You are especially looking for factors that are square numbers, or sometimes factors that repeat (repeating factors give you a square number).

√147

=√3·49    Remember 49 is a square number, you can take out its square root.

=7√3       Simplified.

You might also end up with these factors instead.

√147

=√3·7·7      Two same factors mean a square number you can take out.

=7√3         Simplified form.
