Question

please answer the questions​

Answer 1

Question 1:-

(-3)^-2=1/9

(6)^-1=1/6

Let the number multiplied be x,

then,(1/9)*x=(1/6)

x=9/6=3/2

Hence number to be multiplied is 2/3.

Question 2:-

[ 7 ^(2x+1)]/49=343

[7^(2x+1)]/7^2=7^3

Hence we will subtract the power,

7^(2x+1-2)=7^3

7^(2x-1)=7^3

Hence,2x-1=3

2x=4

x=2

Hope it helps you.
