Answer 1

7 sig figs.

Step-by-step explanation:

Hello,

By performing the given operation:

`12.34*56.78`

The result is:

`12.34*56.78=700.6652`

Thus, we notice that 700.6652 has five non-zero digits which are eligible for significant figures. Moreover, those two zeros after the 7 also are eligible for significant sigures as they are to the right of the first non-zero digit (7). Therefore, the result contains seven (7) significant figures.

Best regards.
