Step-by-step explanation:
The question seem incomplete;
The full question is
<em>Which expression is equivalent to 4√6/3√2 </em>
<em></em>
Given
4√6/3√2
Required
Find equivalent
Rewrite Expression
Expand the above expression
Further split the fraction
Using rule of surds;
So, the above expression becomes
At this stage, the expression cannot be further simplified;
Hence, 4√6/3√2 =
<span>4. Simplify the expression.
sine of x to the second power minus one divided by cosine of negative x</span>
</span>sin2x+cos2x=1</span> <span>1−sin2x=cos2x<span>
</span>cos2(x)/(sin(x)−csc(x))</span> <span>csc(x)=1/sin(x)</span> <span>cos2(x)/(sin(x)− 1/sin(x))= cos2(x)/((sin2(x)− 1)/sin(x))</span> <span>sin2(x)− 1=-cos2(x)</span> <span>cos2(x)/(( -cos2(x))/sin(x))
=-sin(x)</span>
<span>the answer is the letter a) -sin x
