any intelligents plssssss answer,plsss​

Answer 1

Answer:

the product of 1/2 m²n² ×(-10mn³) is -40

Answer 2

Answer -

• The answer is -40.

To find -

• The value of (1/2 m²n²) × (-10 mn³) and find the value when m = 2 and n = 1.

Step-by-step explanation -

• Here, the value of m and n are given to us. So first, let's find the product of 1/2 m²n² and -10mn³. Then we will substitute the value of m and n in the algebraic expression and solve it to find out our answer!

$\longmapsto\sf \bigg( \dfrac{1}{2} {m}^{2} {n}^{2} \bigg) \: \bigg( - 10m {n}^{3} \bigg)$

$\longmapsto \sf \dfrac{1}{2} {m}^{2} {n}^{2} \: \bigg( - 10m {n}^{3} \bigg)$

$\longmapsto \sf \cancel{\dfrac{ - 10}{ \: \: \: 2}} {m}^{3} {n}^{5}$

$\longmapsto \sf\dfrac{ - 5}{ \: \: \: 1} {m}^{3} {n}^{5}$

$\longmapsto \sf- 5 {m}^{3} {n}^{5}$

Substituting the value of m and n -

$\longmapsto \tt- 5 {m}^{3} {n}^{5}$

$\tt\longmapsto - 5 \times {2}^{3} \times {1}^{5}$

$\tt\longmapsto - 5 \times 8 \times 1$

$\tt \longmapsto- 5 \times 8$

$\tt \longmapsto - 40$

Thus -

• The product of 1/2 m²n² and -10mn³ when m = 2 and n = 1, is -40.
