Question

Which expression is NOT equivalent to the others?

A. 15^2 + 15^1 x 13^1 x 13^1
B. 15^2 x 15^1 x 13^2
C. 15 × 15 × 15 × 13 × 13
D. 15^3 x 13^2

Answer 1

A = 225 + 15 * 13 * 13

A = 225 + 2535

A = 2,760

B = 225 * 15 * 169

B = 570,375

C = 570,375

D = 3375 * 169

D = 570,375

So, A is not equivalent with 2,760 instead of 570,375
