Question

Write 6.92 x 10 (-8 exponent) in standard notation.
A. 0.00000692
B. 0.000000692
C. 0.0000000069
D. 0.0000000692

Answer 1

We are going backwards 8 places, so 6.92 is 0.0000000692. This corresponds to answer D. You need (n-1) zeroes after the decimal point. n is the exponent in standard form. So in the case of 6.92 * 10^8, n would be 8.

Answer 2

6.92 x 10-8 in standard notation= D. 0.0000000692
