Answer 1

1)20% от 1/20  1/20:100*20=0,01
2)3^12*16/3^10*4^3= 3² * 4² * 4³=9*4^5=9216
3)0.2% от 20        20:100*0,2=0,04

Answer 2

1) 20% от 1/20

To find 20% of 1/20, we can multiply 1/20 by 20% (or 0.2).

The calculation would be: 1/20 * 0.2 = 0.05

Therefore, 20% of 1/20 is 0.05.

2) 3^12 * 16 / 3^10 * 4^3

To simplify this expression, we can use the properties of exponents.

The calculation would be: 3^12 * 16 / 3^10 * 4^3 = (3^12 * 16) / (3^10 * 4^3)

We can simplify further by dividing the exponents with the same base: = (3^2 * 3^10 * 16) / (3^10 * 4^3)

Since 3^2 is equal to 9, we can substitute that in: = (9 * 3^10 * 16) / (3^10 * 4^3)

Now, we can cancel out the common factors: = (9 * 16) / 4^3

Simplifying further: = 144 / 64

And the final result is: = 2.25

Therefore, the value of 3^12 * 16 / 3^10 * 4^3 is 2.25.

3) 0.2% от 20 ОТВЕТ ДЕСЯТИЧНОЙ ДРОБЬЮ

To find 0.2% of 20, we can multiply 20 by 0.2% (or 0.002).

The calculation would be: 20 * 0.002 = 0.04

Therefore, 0.2% of 20 as a decimal is 0.04.
