Question

find 7^3×9^3 *
63^6
54^6
63^3. that's MCQ​

Answer 1

Answer:

Let us first detect the rule. We will check the rule on at least 2/3rd of our terms. Now let us see the first term is 32 and the third term is 24. Since the third term is smaller than the first one we can speculate that it has been obtained by a rule that has either subtraction or division involved. Similarly, the second term is got from a rule that has either addition or multiplication in it.

Since the third term is smaller than the first one we can speculate that it has been obtained by a rule that has either subtraction or division involved. Similarly, the second term is got from a rule that has either addition or multiplication in it.We see that 32 + 8 = 40 and 32 – 8 = 24. Now let us check this rule for one more term. We see that 16 + 8 = 24. Therefore this works for more than half of the given numbers. Hence the rule is correct. Therefore the missing number in the series is 16 – 8 =  8. The answer is D) 8.

Answer 2

Answer:

$\sf \: {7}^{3} \times {9}^{3} \\ \red \implies \bf \: (7 \times 7 \times 7) \times( 9 \times 9 \times 9)$

$\red \implies \bf \: {63}^{3}$
