Add 2^29 to both quantities: Quantity A: 2^30 Quantity B: 2^29 + 2^29

ASIDE: Quantity B features the sum of two identical values, which is the same as 2 times one value. For example, k + k = 2k, and 3w + 3w = (2)(3w) So...

Simplify Quantity B to get: Quantity A: 2^30 Quantity B: (2)(2^29)

Simplify again to get: Quantity A: 2^30 Quantity B: 2^30
