Question

by what number should (-4)power -1 be multiplied so that product becomes 10 power -1​

Answer 1

Answer:

-2/5

Step-by-step explanation:

Let the number multiplied be x.

According to Question,

(-4)^-1 × x = (10)^-1

=> -1/4 × x = 1/10

=> x = 1/10 × -4

=> x = -2/5

Hence, (-4)^-1 should be multiplied with -2/5 so that product becomes (10)^-1.
