To simplify √((2x)^2)√2y, we
must multiply the indices of both roots and the coefficients that within both roots. As we can see bellow, we get a root which has index 4:
=((2x)^(2y))^1/4
Finally, the factor (2x)^2 has an exponent which is divisible by the index of the root, so it can be simplified, as it's shown in the following step:
=
(2x)(2y)^1/4
6x=18
1/5x=25
8+x=22
2/3x =12
4x+4=2x. 2x=-4
x+1/4x=150. Or 5/4x =150
3x-45=30
1/2x-14=x+2
Answer:
11 marbles
Step-by-step explanation:
Let x = no. of marbles-Alex
3x = no. of marbles-Billie
3x - 9 = no. of marbles-Chris
x + 3x + 3x - 9 = 68
7x - 9 = 68
7x = 77
x = 11
Answer:
He must recruit 35 people
Step-by-step explanation:
43.75/1.25
1.25*30=37.50
1.25*5=6.25
37.50+6.25 = 43.75
