Question

-1000m⁴n⁷×(0,2m n ³)при m=2,n=-1​

Answer 1

Ответ:

-6400

Объяснение:

-1000m⁴n⁷×(0,2m n ³)                           при m=2,n=-1​

-1000m⁴n⁷×(0,2m n ³)  =-200m^5n^10

-200m^5n^10=-200*2^5*(1)^10=-200*32*1=-6400

Answer 2

To evaluate the expression $-1000m^4n^7 \times (0.2mn^3)$ when $m = 2$ and $n = -1$, we can substitute the values of $m$ and $n$ into the expression and then perform the calculations:

Given expression: $-1000m^4n^7 \times (0.2mn^3)$

Substitute $m = 2$ and $n = -1$: $-1000 \times (2^4) \times (-1)^7 \times (0.2 \times 2 \times (-1)^3)$

Simplify the terms: $-1000 \times 16 \times (-1) \times (0.2 \times 2 \times (-1))$

$-16000 \times (-1) \times (-0.4)$

$16000 \times 0.4$

$6400$

Therefore, when $m = 2$ and $n = -1$, the value of the expression $-1000m^4n^7 \times (0.2mn^3)$ is $6400$.
