1. You could break them up:
10+30+20+10=70
6+5+4+4=19
70+19=89
2. Separate to groups:
16+35=51
24+14=38
51+38=89
Answer:
Step-by-step explanation:
radius (r) = 4 cm
area of the circle
= π * r²
= 3.14 * 4 * 4
=50.24 cm²
hope it will help :)
For the exponential expression,
the simplified value is 2.

How to simplify the exponential expression?</h3>
First, we need to remember a rule for exponential expressions, it says that:
![x^{1/n} = \sqrt[n]{x}](https://tex.z-dn.net/?f=x%5E%7B1%2Fn%7D%20%3D%20%5Csqrt%5Bn%5D%7Bx%7D)
Then we can rewrite the given exponential expression as:
![16^{1/4} =\sqrt[4]{16}](https://tex.z-dn.net/?f=16%5E%7B1%2F4%7D%20%3D%5Csqrt%5B4%5D%7B16%7D)
So, we just need to find a number that when multiplied by itself 4 times, is equal to 16.
We know that:
2*2 = 4
Then:
2*2*2*2 = 2⁴ = 4*4 = 16
Then we can conclude that:
![16^{1/4} =\sqrt[4]{16} = 2](https://tex.z-dn.net/?f=16%5E%7B1%2F4%7D%20%3D%5Csqrt%5B4%5D%7B16%7D%20%3D%202)
So the simplified value of the exponential expression is 2.
