Question

4x2 - 12 ÷ y - (7 + 15)

What is the value of the expression when x = 6 and y = 6?

Answer 1

Answer: 8168

4^6 x2-126-(7+15) <-write expression in exponential form with the base of 2

2^12 x2-12 ÷ 6-(7+15) <- rewrite

2^12 x 2 - 2 - 22 <-- calculate

2^13 - 2 - 22 <-- evaluate the power

8192 -2 -22 <-- calculate the difference
