Question

(100,000(1+6.70÷100)^9)−100,000​

Answer 1

Answer:

$= \frac{67}{ {10}^{14} }$=0.00000000000067

Step-by-step explanation:

convert the decimal number into a fraction

$6.7 = \frac{67}{10}$

write in exponential form

$= 100000(1 + \frac{67}{10 \times {100}^{9} } ) - 100000$

calculate the product

$= 100000(1 + \frac{67}{10 \times {10}^{18} } ) - 100000$

multiply each term by 100000

$100000 + \frac{67}{ {10}^{14} } - 100000$

eliminate the opposites

$= \frac{67}{ {10}^{14} }$

= 0.00000000000067
