The second power of (X-2) = 16 to find x The third power of (1-x) = - 0.027 20 / 7 + 3 times root sign 2-2 / 2 Pai (3.14159) accurate to 0.1 If the absolute value of 2a-3 and the root B-2 are opposite to each other, find the value of the cubic power-4a of B Given y = radical X-2 + radical 2-x + 4, find the value of Y power of X It is known that the square root of X is 2A + 3 and 1-3a, and the cube root of Y is a. find the value of X + y Given that M satisfies the quadratic power of 16m - 25 = 0, find the square root of 4m + 5
1. X-2 = + 4 or X-2 = - 4, x = 6 or x = - 22.1-x = - 0.3, x = 1.33. Press calculator. 4. Absolute value and root sign are greater than or equal to 0, opposite numbers are both 0. A = 3 / 2, B = 2, the answer is 25, root sign should be greater than or equal to 0. So x can only be 2, so x = 2, y = 4, the answer is 166
