Question

(3 x 10^4) (4 x 10^23)

Answer 1

$\\ \sf\longmapsto 3\times 10^4\times 4\times 10^{23}$

$\\ \sf\longmapsto 3\times 4\times 10^4\times 10^{23}$

$\\ \sf\longmapsto 12\times 10^{23+4}$

$\\ \sf\longmapsto 12\times 10^{27}$

Answer 2

Answer:

$(3 \times {10}^{4} )(4 \times {10}^{23} ) \\ 3 \times 4 \times {10}^{4 + 23} \\ = 12 \times {10}^{27}$
