Exponents of Real Numbers Exercise 2.29
Solution 1
{2 - 3(2 - 3)3}3
= {2 - 3(-1)3}3
= {2 - 3(-1)}3
= {2 - (-3)}3
= {2 + 3}3
= {5)3
= 53
= 125
So, correct option is (b).
Solution 2
x = 2, y = -2
x - y = 2 - (-2) = 2 + 2 = 4
Now x - yx-y = 2 - (-2)4 = 2 - 16 = -14
So, correct option is (d).

Solution 7
Solution 8
8x+1 = 64 = (8)2
so, x + 1 = 2
Hence, x = 1
Now, 32x + 1 = 32(1) + 1 = 33 = 27
Hence, correct option is (d).
