Answer 2

Answer:

GIVEN:

$(5.6 \times 10 {}^{5} ) \times (6.9 \times 10 {}^{8} )$

we have to find the value of of the above question

SOLUTION :

$(5.6 \times 10 {}^{5} ) \times (6.9 \times 10 {}^{8} ) \\ \\ = 5.6 \times 6.9 \times 10 {}^{5} \times 10 {}^{8} \\ \\ = (5.6 \times 6.9) \times 10 {}^{5 + 8} \\ \\ = 40.71 \times 10 {}^{8}$

We know that when the bases are same then the power get add together.

We have to first arrange them in pair as it has been done above.

By using this formula we can evaluate the the question.

if you have any doubt regarding this then comment!

$answer \: is \: 40.71 \times 10 {}^{8}$
