Question

write the following in an exponential form with a negative exponent: 121/64 ​
please answer

Answer 1

Answer:

64 - 121 =-57

Step-by-step explanation:

it is because to prove a negative exponent first we have to subtract from divisor to divident

Answer 2

Step-by-step explanation:

Given :-

121/64

To find :-

Write the following in an exponential form with a negative exponent?

Solution :-

Given that

121/64

121 can be written as 11×11 = 11²

64 can be written as 8×8 = 8²

So, 12/164 can be written as

=> 11²/8²

=> (11/8)²

Since (a/b)^m = a^m / b^m

It can be written as

=> 1/(8/11)²

=> (8/11)-²

Since , a^-n = 1/a^n

Therefore, 121/64 = (8/11)-²

Answer:-

The exponential form with a negative exponent of 121/64 = (8/11)-²

Used formulae:-

→ (a/b)^m = a^m / b^m

→ a^-n = 1/a^n
