Step-by-step explanation:
Using the Cosine equation (CAH) you type in a calculator "cos(x) = 4.5/7.8".
This will get you the answer if typed in a calculator and hitting "SOLVE".
The value of the expression is
.
Solution:
Given expression:

<u>To find the value of the given expression:</u>
Using exponent rule: 


Using exponent rule: 


Since 


Hence the value of the expression is
.
To multiply exponents with like bases, simply add the exponents...
3^-3 × 3^4 × 3 × 3^-5 =
add exponents across, remember just 3 means 3^1.
-3 + 4 + 1 + -5 = -3
answer is 3^-3
It is C bc it is on the opposite side and on the outside
