Answer 1

3)P
4)
$(1.5 times {10}^{ - 3} ) times (5 times {10}^{ - 2} ) = \ = 1.5 times {10}^{ - 3} times 5 times {10}^{ - 2} = \ = frac{3}{2} times {2}^{ - 3} times {5}^{ - 3} times 5 times {10}^{ - 2} = \ = frac{3}{2} times frac{1}{ {2}^{3} } times frac{1}{ 125 } times 5 times frac{1}{100} = \ = frac{3}{2500 times {2}^{4} } = \ = frac{3}{2500 times 16} = \ = frac{3}{40000} = \ = 0.000075$
