Question

Quizplus · Accepted Answer

To convert a number in scientific notation to ordinary decimal notation, we move the decimal point to the left if the exponent is negative. In this case, we have $( 5.26 ) ( 10 ) ^ { - 2 } = 0.0526$ since the exponent is negative and we move the decimal point two places to the left. Therefore, the best choice is E.

Write (5.26)(10)−2( 5.26 ) ( 10 ) ^ { - 2 }(5.26)(10)−2

Write $( 5.26 ) ( 10 ) ^ { - 2 }$
