When you take a normal square root, that's also the same is raising to the 1/2 power. So you need the 5th root of 15, or 15^(1/5) = 1.71877...
BUT, multiplication comes first, order of operations
so 2.24 * 2 = 4.48
Add 15^(1/5) to 4.48 and keep as many decimals as you need
Answer:
216
Step-by-step explanation:
Plug in 1 to f(x). 2(1) + 4 = 6
Plug that answer in to h(x).
6^3 = 6*6*6 = 216

Answer:
Step-by-step explanation:
Step1: isolate the square root on the left hand side.
Original equation :x+1=√-6x-6
Isolate :x+1=√-6x-6.
Step2: raise both sides to the second power.
(x+1)^2=(√-6x-6)^2
(x+1)(x+1)=-6x-6
Step3: after squaring, solve the quadratic equation.
x^2+2x-1=-6x-6
x^2+8x+7=0
x^2+7x+x+7=0
x(x+7)+1(x+7)=0
(x+1)(x+7)=0
x=-1,-7
Step4:check that the first solution correct.
Input x=-1 into the original equation
x+1=√-6x-6
-1+1=√+6-6
0=0
Step5:check that the second equation is correct.
Input x=-7 into the original equation
x+1=√-6x-6
-7+1=√42-6
-6=√36
-6#6
Therefore one solution is found.
x=-1
Answer: 98268
Step-by-step explanation:
Given: In an international company,
Employees in one country = 22,700
If this is 23.1% of the total number of company's employees,
[ , replace 'of' by '×']
i.e. 23.1% of (total employees) = 22700
Hence, there are 98268 employees in total.
