A) x^5/6 ≠ 5√6, Because 5 is in numerator & 6 in denominator in exponential expression so it can be in direct expression.
It is False.
b) (16)^1/4 = 2.
It is False
c) a^2/7 + a^4/7 = a^2/7+4/7 = a^6/7
It is False.
d) Here, powers are not equivalent.
Again, It is False
e) (27x^6)^2/3 = 27^2/3 x^12/3
= 9x^4
It is True.
13) Here, expression would be: a^2/3
In short, Your Answer is Option B
14) ∛8x^6
= ∛8 x^6/3
= 2x²
In short, Your Answer would be Option C
Hope this helps!
Answer:
-15.6 or -15 3/5
Step-by-step explanation:
Answer:
A. The stepwise selection procedure uses Adjusted R-square as the "best" model criterion.
Step-by-step explanation:
Stepwise regression is a model which uses variables in step by step manner. The procedure involves removal or inclusion of independent variables one by one. It adds the most significant independent variable and removes the less significant independent variable. Usually stepwise selection uses R-square or Mallows Cp for picking the best fit.
