Question

By what number should (3/5)^-2 be multiplied to get (3/2)^-2
Plz solve step by step​

Answer 1

Answer:

2^-3 = 1/ (2^3) = 1/ (2×2×2) = 1/8

Let the number to be multiplied by (2^-3) to get the answer 5 be ‘n'

Thus,

n × (2^-3) = 5

which means,

n × (1/8) = 5

Multiplying both LHS and RHS by 8, we get

8 × n × 1/8 = 5 × 8

That means,

n = 40.

We should multiply (2^ -3) by 40 to get 5
