(2*10²)⁴ * (19*10) ⁻⁶﻿

$(2 \times 10 ^{2} )^{4} \times (19 \times 10) ^{ - 6} = 16 \times 10 ^{8} \times 19 ^{ - 6} \times 10 ^{ - 6} = 16 \times 10 ^{8} \times \frac{1}{19 ^{6} } \times 10 ^{ - 6} = \frac{16 \times 10 ^{8} \times \times 10 ^{ - 6} }{19 ^{6} } = \frac{16 \times 10 ^{2} }{19 ^{6} } = \frac{16 \times 100}{19 ^{6} } = \frac{1600}{19 ^{6} }$
