Which expressions are equal to 6^3 4^1/4^3 me asap

We will be using division property of exponents.

The property is as follows:

This means if we have same base in both numerator and denominator, the exponents will get subtracted.

In our question we have

Now we will use another property of exponents here:

So if we take reciprocal of the above expression we will get,

Rewriting the final

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1
