The sentence is a second conditional (imaginary/unreal situation in the present), using "if + past tense" and "would + base verb".

Since it says "if the weather were good", the correct structure is: "We would play football."

Explanation

Given:

log₈₁ 9 = x

We can rewrite this in exponential form:

81^x = 9

Since 81 = 9², we can rewrite:

(9²)^x = 9

9^(2x) = 9¹

Equating the exponents:

2x = 1

x = 1/2

x = 0.5

Explanation

The Law of Exercise, proposed by Edward Thorndike, includes two sub-laws: Law of Use (practice strengthens learning) and Law of Disuse (lack of use weakens learning).

Explanation

Diamond is an excellent conductor of heat due to strong covalent bonding and crystal structure.

It is a strong electrical insulator because it lacks free electrons to carry current.

Explanation

The thickness of Earth is about 13,700 kilometers (8,500 miles).

The mantle, which is the biggest part of Earth by volume, is approximately 2,900 kilometers (1,800 miles) thick. 

Explanation

Let's find the selling price (SP) after a 5% discount on the marked price (MP).

MP = Rs. 72,000

Discount = 5% of MP = 0.05 × 72,000 = Rs. 3,600

SP = MP - Discount = 72,000 - 3,600 = Rs. 68,400

The shopkeeper earned a 14% profit on the cost price (CP). Let's denote CP as x.

SP = CP + Profit

68,400 = x + 0.14x

68,400 = 1.14x

Now, find CP:

x = 68,400 / 1.14

x = 60,000
