(-sinx)

Step-by-step explanation:

The given expression is cox²x cosecx - cosecx

We have to simplify it

= cos²x $(\frac{1}{sinx})-(\frac{1}{sinx})$

= $\frac{cos^{2}x }{sinx}-\frac{1}{sinx}$

= $\frac{1}{sinx}$ × (cos² x-1)

= - $\frac{1-con^{2}x}{sinx}$

= - $\frac{sin^{2}x}{sinx}$

= - sinx

Therefore, (-sinx) is the answer.

a) 48

b) 37

Step-by-step explanation:

a) 16 and 64 is $4^{2}$ and $8^{2}$

64-16=48

b) 27 and 64 is $3^{3}$ and $4^{3}$

64-27=37
