Next

Please fill out the fields marked in red.

−r² / 2s⁵
−r² / −2s⁵
r² / 2s⁵
s⁵ / −2r²

Explanation

Well done !

Explanation:

14r¹²s¹⁵ ÷ − 28r¹⁰s²⁰
=

14r¹²s¹⁵ / − 28r¹⁰s²⁰

=

− 1 / 2

r¹² / r¹⁰

s¹⁵ / s²⁰

=

− 1 / 2

r²

s¹⁵ / s²⁰

=

− 1 / 2

r²

1 / s⁵

=

−r² / 2s⁵

Step by step working:

−14 / 28

r¹² / r¹⁰

s¹⁵ / s²⁰

[Simplify constant term]

−14¹ / 28₂

=

− 1 / 2

[Simplifying r terms]

r¹² / r¹⁰

= r^{12 − 10} = r²
[Simplifying s terms]

s¹⁵ / s²⁰

= s^{15 − 20} =

1 / s⁵

∴

14r¹²s¹⁵ / − 28r¹⁰s²⁰

=

−r² / 2s⁵

Explanation

Wrong answer !

The correct answer is :

−r² / 2s⁵

Explanation :

14r¹²s¹⁵ ÷ − 28r¹⁰s²⁰
=

14r¹²s¹⁵ / − 28r¹⁰s²⁰

=

− 1 / 2

r¹² / r¹⁰

s¹⁵ / s²⁰

=

− 1 / 2

r²

s¹⁵ / s²⁰

=

− 1 / 2

r²

1 / s⁵

=

−r² / 2s⁵

Step by step working:

−14 / 28

r¹² / r¹⁰

s¹⁵ / s²⁰

[Simplify constant term]

−14¹ / 28₂

=

− 1 / 2

[Simplifying r terms]

r¹² / r¹⁰

= r^{12 − 10} = r²
[Simplifying s terms]

s¹⁵ / s²⁰

= s^{15 − 20} =

1 / s⁵

∴

14r¹²s¹⁵ / − 28r¹⁰s²⁰

=

−r² / 2s⁵
