Math Literacy G8 Spiral Review MP1-2

Write the answer in scientific notation.
5 x 10⁸ -   3.4 x 10⁸  =

• 2.4 x 10⁸
• 2.4 x 10⁰
• 1.6 x 10⁰
• 1.6 x 10⁸

(2.3 x 10²) + (4.1 x 10³) =

• 433

Which of the following is correct scientific notation?

• 20.35 x 10⁴
• .2035 x 10⁴
• 2035 ⁴
• 2.035 x10⁴

(9.6×10³) × (6.7×10²)

• 64.32×10⁵
• 6.432×10⁶
• 64.32×10⁶
• 64.32×10⁵

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

• Subtract

• Divide

• Multiply

• Add

• 10 and 11

• 9 and 10

• 8 and 9

• 7 and 8

How do you solve:
(2x⁵)(6x⁴)

• MULTIPLY coefficients
  MULTIPLY exponents
• DIVIDE coefficients
  SUBTRACT exponents
• Combine like terms
• MULTIPLY coefficients
  ADD exponents

According to exponent rules, when we divide two powers with the same base we _______ the exponents.
Example: h⁸ / h³

• add
• subtract
• multiply
• divide

According to exponent rules, when we multiply two powers with the same base we _______ the exponents.

Example: c⁶ ⋅ c⁴

• add

• subtract

• multiply

• divide

Simplify so there are no negative exponents in the answer.

 $\left(x^4\right)^2x^{-3}$  

•  $x^5$  

•  $\frac{1}{x^{18}}$  

•  $-x^5$  

•  $\frac{1}{x^{15}}$
