Question 1 The correct answer is D. The power of ten. Exponential notation is a way of expressing numbers that are too big or too small to be conveniently written in decimal form. It is used for numbers with a large number of zeroes, either before or after the decimal point. Question 2 The correct answer is A. Exponents are placed to the right of the base number and are written a little above the line of text. Question 3 The correct answer is B. The exponent tells you how many times the number is multiplied by itself. In the case of 8,000,000, it can be written as 8 times 10 raised to the power of 6 (8 x 10⁶), as there are six zeroes in the number. Question 4 The correct answer is A. Since 4,000 can be written as 4 x 10³, it means that it would represent 3 place value columns. Each increment in the exponent represents a shift in the place value. Question 5 The correct answer is C. The number 45,000 can be written in exponential notation as 4.5 x 10⁴. This is because 45,000 is the same as 4.5 times 10,000, and 10,000 is 10 to the 4th power.
