Question

select all the correct answers.

which of these numbers are less than (8.1 \times 10^{-8})?

(8.2 \times 10^{-8})
(7.3 \times 10^{-5})
(9.2 \times 10^{-9})
(3.4 \times 10^{-10})

Explanation:

Identify the target value

We need to find which of the given options are strictly less than the target value:

$$ T = 8.1 \times 10^{-8} $$

Compare the first option
