Question

X
find the value of x,
for which(7/12)-4×(7/12)3x=(7/12)5​

Answer 1

Answer:

Given (127)−4×(127)3x=(127)5

Since the base term in equation is same, according to laws of exponents we can equate them as

−4+3x=5

Now shift the −4 to R.H.S it becomes 4

⇒3x=5+4

⇒3x=9

Now sahift 3 to R.H.S

⇒x=39=3
