Multiplicative inverse of 7-2 is _________a)49 b)5 ...
To find the multiplicative inverse of 7-2, we need to find a number that when multiplied by 7-2 gives us 1 as the product.
Let x be the multiplicative inverse of 7-2, then we have:
(7-2) * x = 1
Expanding the left-hand side, we get:
7x - 2x = 1
Simplifying, we get:
5x = 1
Dividing both sides by 5, we get:
x = 1/5
Therefore, the multiplicative inverse of 7-2 is 1/5, which is equivalent to 0.2 or 20%.
Option A, 49, is not the correct answer.

Multiplicative inverse of 7-2 is _________a)49 b)5 ...
Correct answer is option A
7^-2 can be written as 1/7^2(according to the exponent rule = a^-N is same to as 1/a^n)
so 1/7^2 = 1/49
reciprocal of 1/49 = 49/1 (49)
