What’s the answer to these questions? !

A is 6x12y4

B is 4x4z15

C is 12a18b10

and D is 6s20t2

1)3 x 2 = 6

x2 x x6 = x12

y4 x y = y4

2) 4 x 1 = 4

x x x4= x4

z3x z5 = z15

3) 4 x 3 = 12

a3 x a6 = a18

b2 x b5 = b10

4) 6 x 1= 6

s5 x s4 = s20

t x t2= t2

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°
