Answer :
Answer: - 2 b
Step-by-step explanation:
Here the given expression,
[tex]\frac{12xayb}{-6xay}[/tex]
= [tex]\frac{12\times x\times a\times y\times b\times x^{-1}\times a^{-1}\times y^{-1}}{-6}[/tex] [tex]( \frac{1}{a^x} = a^{-x} )[/tex]
= [tex]-2 x^{1-1}\times a^{1-1}\times y^{1-1}\times b[/tex]
[tex](a^m\times a^n = a^{m+n})[/tex]
= [tex]-2\times x^{0}\times a^{0}\times y^{0}\times b[/tex]
= [tex]-2 \times b[/tex] [tex]( a^0 = 1 )[/tex]
= [tex]- 2b[/tex]
Answer:
-2b is the answer.
Step-by-step explanation:
Given expression is
12xayb / (-6xay)
We have to simplify above expression.
We use two formulas to simplify above expression.
[tex]1/x^{m}=x^{-m}[/tex] (formula 1)
[tex]x^{m}[/tex]×[tex]x^{n}[/tex]=[tex]x^{m+n}[/tex]
using (formula 1) in given epression, we get
2×6 × x × a × y × b × x⁻¹ × a⁻¹ × y⁻¹ / (-6)
using (formula 2) in given expression,we get
-2 x⁽¹⁻¹⁾ × b × a ⁽¹⁻¹⁾ × y⁽¹⁻¹⁾ ∵x⁰ = 1
-2×1×b×1×1
-2b is the answer.
