A blood platelet is about 2.5 × 10^-6 m wide. Express this width in millimetres in standard form, given that 1 m = 1000 mm.

Question

Accepted Answer

2.5 × 10^-3 mm. Multiply by 1000 = 10^3: 2.5 × 10^-6 × 10^3 = 2.5 × 10^-6+3 = 2.5 × 10^-3 mm. Subtracting the 3 instead of adding it gives the trap 2.5 × 10^-9 mm, which would make the platelet look smaller in millimetres than in metres.

A blood platelet is about $2.5 \times 1 0^{- 6}$ m wide. Express this width in millimetres in standard form, given that 1 m = 1000 mm.
