Question

by what number should (−4)−1 be multiplicated that product becomes 10−1​

Answer 1

Answer:

Step-by-step explanation:

Let the no. be X

[(-4)-1]×X = 10-1

4×X = 9

X = 9/4

9/4 should be multiplicated by (-4)-1 to get 10-1.

Hope it helps.

Answer 2

Answer:

2/5

Step-by-step explanation:

Let x should be multiplied by 4^-1

to get the product equal to 10^-1

4^-1 × x = 10^-1

=> x/4 = 1/10

[ Since , a^-m = 1/a^m ]

=> x = 4/10

=> x = 2/5
