Simplify :
Problem 1 :
41/2
Solution :
= 41/2
By writing 4 in exponential form, we get 4 = 22
= (22)1/2
= 2 2 x (1/2)
= 2
So, the answer is 2.
Problem 2 :
2251/2
Solution :
= 2251/2
By writing 225 in exponential form, we get 225 = 152
= (152)1/2
= 15 2 x (1/2)
= 15
So, the answer is 15.
Problem 3 :
641/3
Solution :
= 641/3
By writing 64 in exponential form, we get 64 = 43
= (43)1/3
= 4 3 x (1/3)
= 4
So, the answer is 4.
Problem 4 :
10001/3
Solution :
= 10001/3
By writing 1000 in exponential form, we get 1000 = 103
= (103)1/3
= 103 x (1/3)
= 10
So, the answer is 10.
Problem 5 :
811/4
Solution :
= 811/4
By writing 81 in exponential form, we get 81 = 34
= (34)1/4
= 34 x (1/4)
= 3
So, the answer is 3.
Problem 6 :
321/5
Solution :
= 321/5
By writing 32 in exponential form, we get 32 = 25
= (25)1/5
= 25 x (1/5)
= 2
So, the answer is 2.
Problem 7 :
8-1/3
Solution :
= 8-1/3
By writing 8 in exponential form, we get 8 = 23
= (23)-1/3
= 23 x (-1/3)
= 2-1
= 1/2
So, the answer is 1/2.
Problem 8 :
163/4
Solution :
= 163/4
By writing 64 in exponential form, we get 16 = 24
= (24)3/4
= 24 x (3/4)
= 23
= 8
So, the answer is 8.
Problem 9 :
27-2/3
Solution :
= 27-2/3
By writing 27 in exponential form, we get 27 = 33
= (33)-2/3
= 33 x (-2/3)
= 3-2
= 1/9
So, the answer is 1/9.
Problem 10 :
(2 1/4)-1/2
Solution :
= (2 1/4)-1/2
By converting the mixed fraction into improper fraction, we get
= (9/4)-1/2
= ((3/2)2)-1/2
= (3/2)-1
By flipping the base, we can change the negative exponent as positive.
= 2/3
Problem 11 :
(3 3/8)-2/3
Solution :
= (3 3/8)-2/3
By converting the mixed fraction into improper fraction, we get
= (27/8)-2/3
= ((3/2)3)-2/3
= (3/2)-2
By flipping the base, we can change the negative exponent as positive.
= (2/3)2
= 4/9
So, the answer is 4/9.
