8*8+7*7= 113

Explanation

1 Million is equal to 10,00,000 (10 Lac)

1 billion is equal to 1000 million

1 billion has 9 zeroes

1 billion means ایک ارب 

Explanation

we have to  find the largest number which divide 615 and 963 leaving remainder 6 in each case.

so let us subtract 6 from 615 and 963

⇒ 615−6=609

⇒ 963−6=957

now lets find the HCF

⇒ prime factorisation of 609=29×3×3

prime factorisation of 957=29×3×11

now lets take out the common factors from both the cases

⇒ 29 and 3

x=29×3=87

∴ 87 is the number which will divide 615 and 963 leaving remainder 6 in each case.

Remember what is True: 3 is prime, odd and 2(3) is even

Choice 1 : T and T is TRUE

Choice 2 : T or F is TRUE

Choice 3 : F and T is FALSE

Choice 4 : T and T is TRUE

Explanation

Step 1: Apply the formula (a - b)² = a² - 2ab + b²

(7 - 9)² = (7)² - 2(7)(9) + (9)²

Step 2: Compare with the given options

The correct expansion is (7)² - 2(7)(9) + (9)².

Explanation

The only positive even prime number is 2.

Any number divisible by 2 is by definition an even number.

So, if a number is divisible by an even prime (i.e., 2), it must be even.

Explanation

Step 1: Recall the definition of probability

Probability is a measure between 0 and 1, inclusive.

Step 2: Evaluate the options

15% = 0.15 (between 0 and 1)

2/3 ≈ 0.67 (between 0 and 1)

-0.5 (less than 0)

0.01 (between 0 and 1)

Step 3: Determine which option is outside the valid range

-0.5 is less than 0, which is not valid for a probability.
