поожааалуйста​

Answer 1

Объяснение:

$(1.8 \times 10 {}^{7} ) \times (3 \times 10 {}^{ - 8} ) = 1.8 \times 10 {}^{ - 1} \times 3 = 1.8 \times ( \frac{1}{10} ) \times 3 = \frac{9}{50} \times 3 = \frac{27}{50} = 0.54$

Answer 2

смотри

$(1.8 \times 10 {}^{7} ) \times (3 \times 10 {}^{ - 8} ) = (1.8 \times 3) \times (10 {}^{7} \times 10 {}^{ - 8} ) = 5.4 \times 10 {}^{ - 8 + 7} = 5.4 \times 10 {}^{ - 1} = 5.4 \times \dfrac{1}{10} = 5.4 \times 0.1 = 0.54$
