Answer:
Step-by-step explanation:
In , notice the third term of the quadratic in standard form is formed entirely by .
Therefore, in :
.
Now that we found , we must find . The first term of the quadratic in standard form is formed entirely by . Therefore:
.
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 .
Answer:
Step-by-step explanation:
Any negative exponent can be moved to the other side of the fraction as a positive exponent.
Thus, simply move the negative exponents from the bottom into the numerator to get. -10a^2*b^4*5a^9*b^5. Then, use the exponent rule to get
