Step-by-step explanation:
all angles in triangle add to 180
90+70=160
180-160=20
20÷5=4
Answer:
The given such number is 6.
Step-by-step explanation:
Let the given such number = m
Now, according to the question, the given expression is:

By the LAW OF EXPONENTS:

⇒Here 
or, the given expression becomes ![m^3 = 216\\\implies m = \sqrt[3]{216} = 6](https://tex.z-dn.net/?f=m%5E3%20%3D%20%20216%5C%5C%5Cimplies%20m%20%3D%20%5Csqrt%5B3%5D%7B216%7D%20%20%3D%206)
or, m = 6
Hence, the given such number is 6.
Option C:
is the value of a and b
Explanation:
Given that the expression 
We need to determine the value of a and b
Let us consider the term
and take the prime factorization of the term 648
Thus, we have,
648 divides by 2,

324 divides by 2,

162 divides by 2,

81 divides by 3,

27 divides by 3,

9 divides by 3,

Thus, we have,

Therefore, equating the powers of 2 and 3, we get,

Hence, the value of a and b is 3 and 4
Thus, Option C is the correct answer.
