Which shows the following expression after the negative exponents have been eliminated?

Option 1. is the correct option.

Step-by-step explanation:

We have to simplify the expression given by eliminating negative exponents.

expression is where m ≠ 0 and n ≠ 0.

As we know powers of same terms add when we multiply them

Now we multiply numerator and denominator by n then expression becomes

Therefore the answer is .

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°

hope this
