Question

find the value of x such that 1/49×7power2x=7⁸​

Answer 1

Answer:

x=5

Step-by-step explanation:

1/49×7^2x=7^8

1/7^2×7^2x=7^8

7^-2×7^2x=7^8

a^m×a^n=a^m+n

7^-2+2x=7^8

since bases are same, equate the powers

-2+2x=8

2x=8+2

2x=10

x=10/2

x=5

Answer 2

Step-by-step explanation:

using laws of exponent like :a^x/a^y=a^x-a^y

you can solve it
