Answer:
Step-by-step explanation:
if 36^12-m=6^2m , find the value of m
To make the exponents equal , we need to get the same base.
The base of both sides of equation are not same.
36 can be written as 6^2
now base of both sides are same . so we equate the exponents
add 2m on both sides
divide by 4 on both sides
The value of m is 6
Given:
He does mistake in the order of giving preference.
We should give preference in the order, division, multiplication, addition, subtraction.
But, he gave the first preferrence to the subtraction.
72-8=64
Next, he used division
64/2=32
Next he adds 32 with 8.
So, he gets 50.
But the actual simplification is,
Simplifying we get,
Hence, the correct value of the expression is 86.
