Question

solve using properties of exponents
​

Answer 1

Answer:

7*(10^-6)>129*(10^-7)

Step-by-step explanation:

1. Change the expression to exponential notation: 7*(10^-6) & 1.29*(10^-9)

2. Shift the decimal of the significand such that the power of 10 becomes equal: 7*(10^-6) & 0.00129*(10^-6)

3. As the powers of 10 are now equal, just compare the significands:

7 & 0.00129

=>7>0.00129

=>7*(10^-6)>129*(10^-7)

...Finally, Done!
