Given that the a power of 10 is equal to 20, and the B power of 10 is equal to 1 / 5, find the value of the a power of 9 divided by the 2B power of 3

Because 10 ^ a = 20, 10 ^ B = 1 / 5, so
10^(a-b)=10^a/10^b=20/(1/5)=100=10^2,
So A-B = 2, so
9^a/3^2b=3^2a/3^2b=3^(2a-2b)=3^2(a-b)=3^4=81.

The 2013 power of 3 - the 2012 power of 6 × 3 + the 2011 power of 9 × 3 is equal to

3 to the 2013 power - 6 × 3 to the 2012 power + 9 × 3 to the 2011 power
=3^2011*(3^2-6*3+9)
=3^2011*(9-18+9)
=0

Calculation: (- 1's 2010 power) + (- 1's 2011 power) + (- 1's 2012 power) is equal to?

Equal to 1
(- 1's 2010 power) = 1
(- 1's 2011 power) = - 1
(- 1's 2012 power) = 1

-What is the - 2 power of 1?

It's equal to one. Take the square of - 1 as the denominator and 1 as the numerator

What is the - 2 power of - 1? Come on, come on!

Remember the formula:
The - nth power of a = (1 / a) to the nth power
For example, the - 3 power of (- 1 / 2) is equal to the third power of (- 2)
So the - 2 power of - 1 = - 2 of (- 1) = 1

-What is the - 1 power of 1 / 2

-2

What is the 2005 power of minus 2 times the 2006 power of 1 / 2 Tonight!

The second is the negative 2 of 2005
=The 2005 power of negative 2 × the 2005 power of 1 / 2 × 1 / 2
=(- 2 × 1 / 2) to the power of 2005 × 1 / 2
=The 2005 power of (- 1) × 1 / 2
=-1/2

What is the minus 2 power of minus 1 / 2

4. First find the second power of (- 1 / 2) to get 1 / 4, and then find the reciprocal to get 4
