Answer:
122+42x= 2( 61+21x)
4x+16x+24 = 4(5x+6)
24x+48-3x = 21x+48
3x+39-2x = x+29

Answer:
D
Step-by-step explanation:
since it's a multiplication consider the two factors one by one
cubic root of y^6 = y^(6/3) = y^2
cubic root of 8x^3= 2x^(3/3)= 2x
so 2xy^2
the correct question in the attached figure
(2^5)/8=2^2
we have
8----------- >2^3
(2^5)/8----------- > (2^5)/(2^3)=2^(5-3)=2^2
therefore
2^2=2^2-- ------> is ok
the answer is by simplifying 8 to 2^3 to make both powers base two and subtracting the exponents
