<3 +<4= 180
<3+25+52=180 from here <3=180-77=103
using this in first equation: 103+<4=180 <4=180-103=77
as you can see <4=77 which is the the sum of 25+52

The answer is 8
Here's why:

The exponents are subtracted one from another when divided.

We can look at the problem this way:

Since we have the power of -1 on the 3, we apply this rule:

Also this rule because we have the power of 1 on the 6:

Then we get this:

We apply the rule:

We get this:
40.47×100=4047 so just multiply it and the the answer is 4047
