Answer:
Multiply 4 by the difference of 10 and 3, then add 5
Is the 2 an Exponent or is it something else
]
The solutions of the equation 
² - 16 = 0is 4/3 and -4/3 and that of the equation 
is 8 and -4.
Solving the both quadratic equations by extracting square roots:
⇒ 
∴ On taking square-root of both sides, we get
= 
⇒ 
and 
⇒ 
= 4/3 and = -4/3
For the equation, , the solution is:
⇒ 
∴ On taking square-root of both sides, we get
⇒ (z - 2) = 6 and (z - 2) = -6
⇒ z = 6 +2 and z = -6 + 2
⇒ z = 8 and z = -4
The solution of the equation is 4/3 and -4/3.
The solution of the equation is 8 and -4.

Answer:
-9√11
Step-by-step explanation:
Simplify 5√11-12√11-2√11
Applying,
The law of surd,
Step 1: factor out the common surd or irrational number i.e √11
√11(5-12-2)
√11(-9)
Step 2: Multiplying the whole number and the surd
-9√11
Therefore,
5√11-12√11-2√11 = -9√11
Hence the right option from the list of option is
c -9√11
