(a) 8.01 × 10⁷

(b) 1.75 × 10^–3

The positive power of 10 denotes the number of terms shifted after the decimal point.

8.01 × 10⁷ = 8, 01, 00, 000

(b) For the standard form notation, only one number is kept before the decimal point and rest all numbers are written after decimal point.

The positive power of 10 denotes the number of terms shifted after the decimal point.
