What is the product of (7 x 10^-5) x (5 x 10^-8) <br> (7 x 10^-5) x (5 x 10^-8) = ? x 10^?

arsen [322]

Answer:

$3.5\times10^-^1^2$

Step-by-step explanation:

$(7 \times 10^-5) \times (5 \times 10^-8)$

Evaluate

$(7 \times 5)\times(10^-^5\times10^-^8)$

$35\times10^-^5^-^8$

$35\times10^-^1^3$

$35\times10^1\times10^-^1^3$

$3.5\times10^1^-^1^3$

$3.5\times10^-^1^2$

Thus, the answer is $3.5\times10^-^1^2$
