Answer:
the answer of this question is " 1 "
Step-by-step explanation:
as
tanx = sinx/cosx
cotx = cosx/sinx
cscx = 1/sinx
after putting them all in the given equation
sinx.(sinx/cosx).(cosx/sinx).(1/sinx)
they all are canceled as all are being multiplied with their reciprocals so answer is " 1 "

Simplify the expression by multiplying exponents

Simplify the expression by cancelling the terms

we have

we know that

so

two solutions
<u>first solution </u>


the first solution is the interval---------> (-1,∞)
<u>second solution</u>




the second solution is the interval---------> (-∞,-1)
therefore
the solution is all real numbers except the number 
the answer in the attached figure
Answer:
61.25
Step-by-step explanation:
2 1/2 is 2.5 in decimal.
24.5*2.5
Multiplying 24.5 by 2.5 gives 61.25
90,000,000 is the answer
