Answer:
x=12
Step-by-step explanation:
(9^5)(9^7)=9^x
282429536481=9^x
<em>Step 1: Flip the equation.</em>
9^x=282429536481
<em>Step 2: Solve Exponent.</em>
9^x=282429536481
log(9^x)=log(282429536481)(Take log of both sides)
x*(log(9))=log(282429536481)
x=log(282429536481)/log(9)
x=12
Step-by-step explanation:
72/64=x/8
=> x = (72×8)/64
=> x = 9.
hope this helps you.
