10 State the number of significant figures in the following : (a) 0.007 m2 (b) 2.64 × 1024 kg

Answer :

(a) The given value is 0.007 m2.

There is only one significant digit which is 7

(b) The significant value is 2.64 × 1024 kg

The power of ten has no bearing on the assessment of significant values. The numbers 2, 6, and 4 are all significant numbers. There are three significant digits.
