Answer 1

Hi Tina,

Divide fraction numerator 5.612 asterisk times 10 to the power of negative 7 end exponent over denominator 9.2 asterisk times 10 to the power of 4 end fraction. Write in scientific notation:

(5.612 x10^-7) / (9.2 x 10⁴)

To divide these, one way is to first divide 5.612 / 9.2 = 0.61

Next you will workout (10^-7 )/ (10⁴)

For this you would subtract the exponents. 10^{(-7 - 4)} = 10 ^-11

Your answer would be 0.61 x 10^-11

For Scientific notation, you should have a digit between 1 and 9 as the first digit.

So you will need to move your decimal place 1 to the right.

This means you subtract one from the exponent.

0.61 x 10^-11 = 6.1 x 10^-12
