If (217 + 217)(417 + 417 + 417 + 417) = 8k, then what is the value of k? Correct Answer 18
Given:
(217 + 217)(417 + 417 + 417 + 417) = 8k
Formula Used:
If ab × ac = ab + C
Calculation:
(217 + 217)(417 + 417 + 417 + 417) = 8k
⇒ 217(1 +1) × 417(1+1+1+1) = 8k
⇒ 218 × 418 = 8k
⇒ 818 = 8k
⇒ k = 18
∴ The value of k is 18.
