A)
= X⁴.X⁵
4 + 5
= x
9
= x
********************************
B 2 + 3
= (2y²).y³= 2 y
5
= 2 y
**********************
C) 2 + 1 3
= (2X²).(3X)= 6 x = 6x
**************************
D)
= (-5y).(-8y²)²
1 4 5
= 40 y y = 40 y
*********************************
E)
3
= X².(XY)= x y
**************************************
F)
= (X²Y).(X³Y²)
2 + 3 1 + 2
= X . Y
5 3
= X . Y
***************************************
G)
= (2X²Y²)(3X²Y²)
2 + 2 2 + 2
= 6 X Y
= 6X⁴Y⁴
********************************
H)
= (3X²Z²).(-2XY).(6Z²)
2 + 1 2 + 2
= - 36 X Y . Z
3 4
= - 36 X . Y . Z
***********************************
I)
= (-2X²)(-4Y²)(-5X³Y⁴)
2 + 3 2 + 4
= - 40 X Y
5 6
= - 40 X . Y
