35
Do 28 squared+21 squared and that equals 1225. Then you do the square root of 1225 and that equals 35
160 = 2 x 2 x 2 x 2 x 2 x 5 = 2^5 x 5
243 = 3 x 3 x 3 x 3 x 3 = 3^5
So
(160 * 243)^1/5
= 5th root of (160 * 243)
= 5th root of (2^5 * 5 * 3^5)
= 2 * 3 * (5th root of 5)
= 6 * (5th root of 5)
Answer is D. 6 * (5th root of 5)
0.14 can be converted to 14/100, which can be simplified to 7/50. (by dividing both sides of the fraction by 2 to simplify it.)
