(2 x 106) x (0.00009) = ?
RSB [31]

I think you meant to write

(2 × 10⁶) × 0.00009

First, convert 0.00009 to scientific notation:

0.00009 = 9 × 10 ⁻⁵

Then

(2 × 10⁶) × 0.00009 = (2 × 10⁶) × (9 × 10 ⁻⁵)

… = (2 × 9) × (10⁶ × 10 ⁻⁵)

… = 18 × 10¹

… = 1.8 × 10²

What is the correct answer to number 7? Please explain and break it down step by step.
a_sh-v [17]

Answer:

The answer to your question is (x + 3)

Step-by-step explanation:

                    \frac{5x + 5}{x} \frac{x^{3}+ 3x^{2}}{x^{2} - 1} \frac{x - 1}{5x}

Factor the expression

                   \frac{5(x + 1)}{x} \frac{x^{2}(x + 3)}{(x - 1)(x + 1)} \frac{x - 1}{5x}

Simplify

Cancel 5 because is in both numerator and denominator                  

Cancel (x + 1) because is in both numerator and denominator                  

Cancel (x - 1) because is in both numerator and denominator                  

Cancel x² because is in both numerator and denominator              

   

After simplifying, the result is  (x + 3)
