f. 9 p^6 q^10

Answer 2

1.
a) 4a²
b) 27p³
c) -16u⁸y⁴
d) -243p¹⁵q¹⁰
e) 8a³b⁶ x 27a⁹b¹⁵ = (8 . 27) a³⁺⁹b⁶⁺¹⁵ = 216a¹²b²¹
f) 24p¹⁰q¹² : 16p⁴q² = (24/16)p¹⁰⁻⁴q¹²⁻² = 1,5a⁶b¹⁰

1)     2u+3u = 5u    ||     3u-2u = u     ||     2u . 3u = 6u²
2)     (u+2)+(u+7) = 2u+9     ||     (u+7)-(u+2) = 5     ||      (u+2).(u+7) = u²+7u+2u+14 = u²+9u+14
3)     (u+1)+(3u+8) = 4u+9     ||    (3u+8)-(u+1) = 2u+7    ||    (u+1).(3u+8) = 3u²+8u+3u+8 = 3u² + 11u + 8
4)      (3u-2)+(2u-4)=5u-6   ||   (2u-4)-(3u-2)= -u-2  ||    (3u-2).(2u-4)=6u²-12u-4u+8 = 6u²-16u+8
5)       (2u-1)+(1-u)=u   || (1-u)-(2u-1)= -3u+2   ||   (2u-1).(1-u) = 2u-2u²-1+u = -2u²+3u-1
