Question

(3,0x10³) x (5x10³ – 15x10⁴) =​

Answer 1

Explicação passo-a-passo:

$(3 \times 10 {}^{3} ) {}^{} \times (5 \times 10 {}^{3} - 15 \times 10 {}^{4} ) =$

$(3 \times 10 {}^{3} ) \times 5.10 {}^{3} (1 - 3.10) =$

$(3 \times 10 {}^{3} ) \times 5.10 {}^{3} (1 - 30) =$

$(3 \times 10 {}^{3} ) \times .10 {}^{3} .( - 29) =$

$10 {}^{3} \times 3. - 29 =$

$10 {}^{3} \times - 87 = 1000 \times - 87 = - 87000$
