Answer 1

See a solution process below:

Explanation:

Equation 1) The decimal point needs to move 2 places to the right, therefore we need to subtract `2` from the 10s exponent:

`-0.07395 xx 10^9 = -7.395 xx 10^7`

Equation 2) The decimal point needs to move 1 places to the left, therefore we need to add `1` to the 10s exponent:

`51.26 xx 10^-7 = 5.216 xx 10^-6`

Equation 3) The decimal point needs to move 3 places to the right, therefore we need to subtract `3` from the 10s exponent:

`-0.004332 xx 10^-8 = -4.332 xx 10^-11`
