Question

watch the which number should be multiplied to 3 power minus 7 so that the product is 3

Answer 1

Hi ,

Let x is the number multiplied with

3^-7 to get the product 3.

x × 3^-7 = 3

x × ( 1/3^7 ) = 3

[ SINCE a^-m = 1/a^m ]

x = 3¹ × 3^7

x = 3^1+8

[ Since a^m × a^n = a^m+n ]

x = 3^8

Therefore ,

Required number = x = 3^8

I hope this helps you.
