Question

If x=(-15)+(-15)+........10 times and y = (-2) × (-2) × (-2) × (-2) × (-2) then x-y = A. -118 B. -182 C. 182 D. 118

Answer 1

Option A: x - y = - 118 is correct

Step-by-step explanation:

Given,

x = (- 15) + (- 15) + (- 15) + ... 10 times

= - (15 + 15 + 15 + ... 10 times)

= - (10 * 15)

= - 150

y = (- 2) × (- 2) × (- 2) × (- 2) × (- 2)

= (- 1)⁵ × (2 × 2 × 2 × 2 × 2)

= - 1 × 32

= - 32

Now, x - y = (- 150) - (- 32)

= - 150 + 32

= - 118

i.e., x - y = - 118

Therefore option (A) is correct.

Note: To solve this type of problems, simply find the product and sum of the given terms, assigned to any arbitrary constant. Then do as asked in the question.
