Answer:
Step-by-step explanation:
The initial expression is:
Using BEMDAS (Brackets - Exponents - Multiplication - Division - Addition -Subtraction), we first start with brackets:
Remember that if there is a negative sign, it will change the signs of the terms within the brackets.
Then, collecting like terms:
Multiply your equation by x/tan(20°) and you get
x = 20/tan(20°)
x ≈ 54.9495
The relevant rules of exponents are
.. (t^a)^b = t^(a·b)
.. t^a·t^b = t^(a+b)
You have
.. (t^-4)^-9·t^2
.. = t^((-4)*(-9) +2)
.. = t^38 . . . . . . . . . . . selection C
<u>Answer</u>
3 square root of 7
<u>Explanation</u>
square root of 3 times square root of 21
√3 × √21 = √(3×21)
= √63
= √(9×7)
= √9 × √7
= 3 × √7
= 3√7
The answer is 3 square root of 7
