Divide in Scientific Notation

What do you do to your exponents when you are dividing in scientific notation?

• Subtract

• Divide

• Multiply

• Add

Divide:
(6.9 x 10⁷) / (2.3 x 10^-3)

• 3 x 10¹⁰

• 3 x 10⁴

• 3 x 10^-4

• 3 x 10^-11

(9.6×10^-8)÷(2×10^-15)

• -4.8×10⁷

• 4.8×10⁷

• 4.8×10^-7

• -4.8×10^-7

Use the expression below to answer Parts A and B. (7.8 imes10^5) div (1.2 times10^9). Part A: Complete a true statement about the expression. The quotient will be ​ ​ (a)   because the exponent of the divisor is ​ (b)   the exponent of the dividend.

• Less than 1

• greater than 1

• equal to 1

• greater than

• less than

• equal to
