Answer:
-(√2)/2
Step-by-step explanation:
The expression evaluated at n=a gives the indeterminate form 0/0, so L'Hopital's rule can be used to find the limit. The second expression comes from differentiating numerator and denominator. Then the form with n=a is no longer indeterminate.
Answer:
6/5 or 1.2
Step-by-step explanation:
you can solve with an equation:
x : 5 = 12 : 50
x = 5 * 12 : 50
x = 6/5 (or 1.2)
or you can solve with an expression
12/50 * 5 = 6/5 (or 1.2)
1/8 is rational because irrational numbers can be written as decimals but not fractions

Answer:
first and fourth
Step-by-step explanation:
x² - 4 = 0 ( add 4 to both sides )
x² = 4 ( take square root of both sides )
x = ± = ± 2
that is x = - 2, x = 2
4x² = 16 ( divide both sides by 4 )
x² = 4 ( take square root of both sides )
x = ± = ± 2
that is x = - 2, x = 2
