An example should help :-
Simplify sqrt 20:-
sqrt 20 = sqrt (4 * 5) = sqrt 4 * sqrt5 = 2 sqrt5
cube root of 54 = cube root 27 * cube root 2 = 3 cube root 2
The rule is to factor the number and look for perfect squares or cubes, etc.
Answer:
B.
Step-by-step explanation:
Yes
26 x 5 - 63 = 67
26 x 3 - 11 = 67
Use m=y2-y1/x2-x1 when you find the slope of two coordinates :)
