In the expression 2.34 x 10⁻³, what does the 4 represent?
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
a. 4/100,000
||\\||\\
b. 4/100
||\\||\\
c. 4
||\\||\\
d. 40 - correct answers✔✔The exponent is a negative, so
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
the decimal is to be moved to the left in three places. In a
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
place value chart, the "4" would be in the one-hundred-
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
thousandths place. The correct answer is A ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
Tom attempts to multiply 23,000 X 45,000 using scientific
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
notation. Which of the following is the correct answer in ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
scientific notation? ||\\||\\ ||\\||\\

||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
B. 9.35 x 10⁸
||\\||\\ ||\\||\\ ||\\||\\
,C. 1.035 X 10⁸
||\\||\\ ||\\||\\ ||\\||\\
D. 1.035 X 10⁹ - correct answers✔✔Change each number
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
into a scientific notation (2.3 X 10⁴ and 4.5 X 10⁴). Then
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
multiply. 2.3 X 4.5 = 10.35. Then add the tens (10.35 X 10⁸) ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\

, A. 49.1
||\\||\\
B. 7.7
||\\||\\
C. 4.9
||\\||\\
D. .5 - correct answers✔✔Round .899 and 9.97 to the
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
nearest tenths as an approximate guess. Which leaves, (1)
