Three to the power of 2019. 3 to the power of 2020 multiplied by 1 to the power of 3 2019 is equal t

Just write 3 to the power of 2019, and you can only calculate that the single digit of 3 to the power of 2019 is 7.

Solution: The 1st power unit of 3 is 3

The 2nd power unit of 3 is 9

The 3rd power unit of 3 is dao7

The 4th power unit of 3 is 1

The 5th power unit of 3 is 3

A single digit is a cycle of four digits.

And: 2019 4=504, remainder.

is 3 so: The single digit of the 2019 power result of 3 is an exponent of 7. When the exponent of the power is negative, it is called "negative exponential power."

The -r power of a positive number a (r is any positive number) is defined as the reciprocal of the r power of a.

For example: 2 to the 6th power = 2 6 = 2 2 2 2 2 2 = 4 2 2 2 2 2 = 8 2 2 2 = 16 2 2 = 32 2 = 64

3 to the 4th power = 3 4 = 3 3 3 3 3 = 9 3 3 = 27 3 = 81 As shown in the above equation, the 6th power of 2 is the multiplication of 6 2s, and the 4th power of 3 is the multiplication of 4 3s.

If you multiply large numbers, you can also calculate it with calculators, computers, and other calculation tools.

Generally speaking, such an answer can be written directly to the power of 3 in 2019, and I can only calculate that the single digit of 3 to the power of 2019 is 7

Untie. Since 1 3 is equal to the minus 1 power of 3, the 2019 power of a 1 3 is equal to the minus 2019 power of -3 by multiplying the power of the same base. The invariant exponents of the base are added so that the power of 1 of the original formula =-3 is equal to a 3

is equal to 9, please refer to the calculation process.

(3) to the power of 2019 (one-third) to the power of 2017 = (-3) to the power of 2019 1/3)^2017=3^2019 . 3^(-2017)

Multiplication and division of powers, multiply with the power of the base, the base does not change, and the exponents are added. Divide by the power of the same base, the base does not change, and the exponent is subtracted.

3 5 to the power of 2019 3 to the power of 5 2020.

The base is still 3 5, and the exponent is: 2019 + 2020 = 4039 so the result is: 3 5 to the power of 4039.

The calculation is as follows: 3 5 to the power of 2019 * 3 to the power of 5 2020.

The title is a bit problematic, it should be 3 5 to the power of 2019 * 5 3 to the 2020 square.

The original formula is equal to 2019 3 5 multiplied by 2019 5 3 and then multiplied by 5 3, and the final result is 5 3.

If you don't understand it, you can write the equation, because 3 5 and 5 3 are reciprocal relationships, multiply two by two to get 1, and finally multiply by 5 3.

Calculate 3 to the power of 5 2019 * 3 to the power of 5 2020 = ?

2019 + 2020 = 4039 power equal to 3 5.

This is a power function, multiplying the same as the power of the base: the base does not change, and the exponents are added. So the answer is 3 5 to the power of 4039.

(2 times the root number 2-3) 219 power x (2 times the root number 2+3) 2019 power x (2 times the root number 2+3) (8-9) 2019 power x (2 times the root number 2+3) -2 times the root number 2+3).

Minus 2 minus the root number three.

The second 2020 becomes 2019 (2+root number 3).

The cubic of 2019 is three 2019 want and family multiplication.

The basic definition of the power is that a is a number, n is a positive integer, and the nth power of a is represented as a?, which represents the result of the search for spring obtained by multiplying n a, such as 2?

2×2×2×2=16。The definition of power can also be extended to the power of 0, to the power of minus, and so on.

2018 2019 is bigger than 2019 2018.

Solution: Let a=2018 2019, b=2019 2018, then a b=(2018 2019) (2019 2018).

Because for n*(1-1(n+1)) n, when n 3, n*(1-1 (n+1)) n 1.

So the code line 2018*(1-1 2019) 2018 1, that is, a b 1, then a b.

So 2018 2019 is bigger than 2019 2018.

Summary. How do you calculate 3 to the power of 2018?

The even power of a negative number is a positive number.
