Answer:
See below.
Step-by-step explanation:
I'll work it out myself, then we should be able to see the mistake:-
6 ∛ (64x^5y^9)
= 6 * 4 * x^(5/3) * y^3
= 24 x^(3/3) * x^(2/3) y^3
= 24 x y^3 ∛(x^2)
You've got confused withe the cube root (∛) on the first line. You've interpreted it as ' 3 times the square root' so you were on the wrong road from the beginning.
Note that y^9 has cube root y^(9/ 3) = y^3 and x^5 has cube root of x^(5/3). The square root of x^9 is x^(9/2).
Answer:
8 friends
Step-by-step explanation:
each get 3 football cards and 4 baseball cards
use hcf method (highest commen factors)
maybe you would do that because 10 divides by multiple things and is a number with a zero as the 2nd digit so you can multiply it by 10 or 100 or 1000 and add a zero to the numerator to make it bigger
Answer:
circumference
Step-by-step explanation:
it's a circle
Answer:
a
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan15° = 
= 
( multiply both sides by x )
x × tan15° = 20 ( divide both sides by tan15° )
x = 
≈ 74.6 ft ( to the nearest tenth of a foot )
