Question

Use your calculator to solve the following. (1.0 x 109) (9.1 x 10-5) / (1.4 x 102)

Answer 1

here we need to solve the given value

`A = ((1.0 * 10^9)(9.1 * 10^(-5)))/(1.4 * 10^2)`

here all above is given with 2 significant digits

so we need to give our final answer by rounding off in 2 significant digits

here we will first multiply the numerator

`A = (9.1 * 10^4)/(1.4 * 10^2)`

now we will perform the division

`A = 6.5 * 10^2`

so the final answer will be 6.5 \times 10^2
