Option A) is correct.

Therefore the simplified given expression

Step-by-step explanation:

Given expression is  

To simplify the given expression:

Above expression can be written as

(since ,anything variable to the power "0' is 1)

   (since )

 (using the property )

Therefore

Therefore Option A) is correct.

Therefore the simplified given expression

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0

step-by-step explanation:

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
