Expression 2222 to the power 7777 + 7777 to the power 2222 is divisible by .

Answer»

Given : 2222⁷⁷⁷⁷ + 7777²²²² (2222 to the power 7777 + 7777 to the power 2222)

To find : 2222⁷⁷⁷⁷ + 7777²²²² is DIVISIBLE by

Solution:

2222⁷⁷⁷⁷ + 7777²²²²

= (1111 * 2) ⁷⁷⁷⁷ + (1111*7)²²²²

Concept USED (ab)ⁿ = aⁿᵇⁿ

= 1111 ⁷⁷⁷⁷ * 2 ⁷⁷⁷⁷ + 1111²²²² * 7²²²²

= 1111 ²²²²⁺⁵⁵⁵⁵ * 2 ⁷⁷⁷⁷ + 1111²²²² * 7²²²²

Concept used aⁿ⁺ˣ = aⁿ * aˣ

= 1111 ²²²² * 11⁵⁵⁵⁵ * 2 ⁷⁷⁷⁷ + 1111²²²² * 7²²²²

Taking 1111 ²²²² as common

= (1111) ²²²² ( 1111⁵⁵⁵⁵ * 2⁷⁷⁷⁷ + 7²²²²)

HENCE divisible by (1111) ²²²²

Hence 2222⁷⁷⁷⁷ + 7777²²²² is Divisible by (1111) ²²²²

Answer» Answer: = (7√3 - 5√2) / (√48 + √18) = (7√3 - 5√2) / (√16.3 + √9.2) = (7√3 - 5√2) / (4√3 + 3√2) = (7√3 - 5√2)/ (4√3 + 3√2). (4√3 - 3√2)/(4√3 - 3√2) = 7√3(4√3 - 3√2) - 5√2(4√3 - 3√2) / 4√3(4√3 - 3√2) + 3√2(4√3 - 3√2) = (28√9 - 21√6 - 20√6 + 15√4) / (16√9 - 9√4) = (28(3) - 41√6 + 15(2)) / (16(3) - 9(2)) = (84 - 41√6 + 30) / (48 - 18) = (114 - 41√6) / 30

7 root 3 -5root 2/ root 48b+root 18

Answer»

Answer:

= (7√3 - 5√2) / (√48 + √18)

= (7√3 - 5√2) / (√16.3 + √9.2)

= (7√3 - 5√2) / (4√3 + 3√2)

= (7√3 - 5√2)/ (4√3 + 3√2). (4√3 - 3√2)/(4√3 - 3√2)

= 7√3(4√3 - 3√2) - 5√2(4√3 - 3√2) / 4√3(4√3 - 3√2) + 3√2(4√3 - 3√2)

= (28√9 - 21√6 - 20√6 + 15√4) / (16√9 - 9√4)

= (28(3) - 41√6 + 15(2)) / (16(3) - 9(2))

Final amount (A) = Rs 2P In Simple Interest, we know that, A = P( 1 + RT) PUTTING the values, we get, 2P = P( 1 + 0.02T) ⇒ 2 = 1 + 0.02T ⇒ 0.02T = 1 ⇒ T = 1/0.02 ⇒ T = 50 The time taken is 50 years.

Meera invests some money at a rate of 2% per year simple interest. How many years does it take for her investment to double in value?

Answer»

Given:

(i) Meera invests some money at a rate of 2% per YEAR simple INTEREST.

To FIND:

(i) TIME taken or her investment to double in value.

Solution:

Given, the principal value (P) = Rs P

Rate (R) = 2% p.a.

Time (T) = ?

Final amount (A) = Rs 2P

In Simple Interest, we know that,

A = P( 1 + RT)

PUTTING the values, we get,

2P = P( 1 + 0.02T)

⇒ 2 = 1 + 0.02T

⇒ 0.02T = 1

⇒ T = 1/0.02

⇒ T = 50

The time taken is 50 years.
